Bodies of three abducted students found in a shallow grave near Hebron, but Hamas denies involvement in murders 
 
 Israeli jets and helicopters launched dozens of air strikes across the Gaza Strip overnight on Monday, just hours after the bodies of three abducted Israeli teenagers were found in a shallow grave near the southern West Bank city of Hebron. 
 
 The air strikes, ostensibly in response to an ongoing barrage of rocket fire from Gaza into southern Israel, came after the Israeli prime minister, Binyamin Netanyahu, vowed the militant Islamist group Hamas, blamed by Israel for the kidnapping, would "pay a heavy price". 
 
 The United Nations human rights office urged on Tuesday all Israelis and Palestinians to exercise "maximum restraint" as the tension across Israel and occupied Palestinian territory escalated. 
 
 Eyal Yifrah, 19, Gilad Shaar, 16, and Naftali Frenkel, 16, who also had US citizenship, went missing while hitchhiking home from their religious schools in settlements on the West Bank on 12 June. 
 
 Their bodies were found by soldiers and volunteers in a valley covered with stones and brush on Monday afternoon. 
 
 The air strikes, which struck 34 locations in the Hamas-run Gaza Strip that Israel says were associated with Hamas and Islamic Jihad, came as troops on the West Bank killed an 18 year-old Palestinian during a raid in Jenin. Israeli authorities claim the teenager was a Hamas member who threw an explosive device at Israeli soldiers. 
 
 In Hebron, meanwhile, it was reported that the Israeli military had blown up the houses of two Hamas members named by Israel as suspects in the abduction Marwan Qawasmeh and Amer Abu Eisheh – the first punitive house demolitions since Israel halted the practice in 2005. The two men disappeared from their homes shortly after the abduction and have not been arrested. 
 
 Following the discovery of the missing Israeli's bodies on Monday, new details about the teenagers' abduction and murder 19 days ago while hitching home from West Bank religious schools have emerged in the Hebrew press, including the fact that investigators believe that the teenagers were killed within a few minutes of getting into a stolen car near Gush Etzion junction. 
 
 According to Israeli media reports, investigators found a bullet casing and other signs consistent with the youths being shot while sitting in the car, which was was later found abandoned and burned only a few kilometres from where their bodies were subsequently discovered. It is believed the three were shot shortly after one of the youths had managed to call an emergency hotline and whisper that they had been kidnapped after being alarmed that the car had made a sudden u-turn. Their bodies were buried in a field near the village of Halhul just north of one of the entrances to Hebron. Israeli officials believe the abductors had planned to trade the bodies for Palestinian prisoners in Israeli jails. 
 
 Binyamin Proper, who was among the civilian volunteers that found the bodies covered with piles of rocks, told Channel 2 TV that a member of the search party "saw something suspicious on the ground, plants that looked out of place, moved them and moved some rocks and then found the bodies. We realised it was them and we called the army". 
 
 The search for the missing teenagers prompted a vast Israeli military operation in the West Bank and the arrest of some 400 Palestinians – mainly Hamas members. The incident has dramatically increased tensions across Israel and the occupied Palestinian territories. 
 
 Prior to the discovery of the bodies, five Palestinians had been killed during the search operation. 
 
 The case, which has received rolling Israeli media coverage, has gripped the Israeli public, prompting mass rallies and a huge outpouring of public sympathy for the mothers of the three teenagers. 
 
 The families of Palestinians killed during the search – some of them also teenagers – have complained that the death of their children have been largely ignored in press coverage. 
 
 Following the discovery of the bodies on Monday, Netanyahu issued a statement once again blaming Hamas. 
 
 "Hamas is responsible, and Hamas will pay ... [They] were kidnapped and murdered in cold blood by wild beasts." 
 
 Israel's economy minister, Naftali Bennett, added his own statement vowing retaliation: "There can be no forgiveness for the killers of children and those who sent them. Now is the time to act." 
 
 For its part, Hamas has denied involvement. Spokesman Sami Abu Zuhri said on Monday: "Only the Israeli version of the events has been published." 
 
 "Israel is attempting to make way for aggression against us, against the Hamas ... No Palestinian group, Hamas or any other group, has taken responsibility for the action, and thus the Israeli version can't be trusted," he added.

 The Israel media reported on Tuesday morning that Netanyahu had faced splits in his Cabinet in its deliberations over how hard to retaliate both for the murders and the increased in rocket fire. 
 
 Senior officials stated both publicly and privately on Monday night and Tuesday morning that Israel was not seeking an "escalation with Hamas", suggesting that despite the rhetoric and the airstrikes in Gaza, retaliation might be limited.Several analysts in the Israeli media, including Amos Harel in Haaretz, have suggested Netanyahu is not keen to get embroiled in a long conflict with Hamas. 
 
 Messages of sympathy continued to come from international leaders who also called for calm. In a statement issue by his office, British prime minister David Cameron said: "I am deeply saddened by the news that the bodies of the three Israeli boys kidnapped on 12 June have been found this evening. 
 
 "This was an appalling and inexcusable act of terror perpetrated against young teenagers. Britain will stand with Israel as it seeks to bring to justice those responsible." 
 
 US president Barack Obama also issued a statement saying: "As a father, I cannot imagine the indescribable pain that the parents of these teenage boys are experiencing." 
 
 "The United States condemns in the strongest possible terms this senseless act of terror against innocent youth. 
 
 "From the outset, I have offered our full support to Israel and the Palestinian Authority to find the perpetrators of this crime and bring them to justice, and I encourage Israel and the PA to continue working together in that effort. I also urge all parties to refrain from steps that could further destabilise the situation. As the Israeli people deal with this tragedy, they have the full support and friendship of the United States." ||||| Story highlights Israel carries out airstrikes against nearly three dozen targets in Gaza

 "Hamas will pay" for the deaths, says the Israeli Prime Minister 
 
 Hamas spokesman warns against escalation 
 
 Tensions between Israel and Hamas ratcheted up Monday after the bodies of three Israeli teenagers, kidnapped this month, were found in the West Bank. 
 
 Israel, in no uncertain terms, blames the disappearances and deaths on Hamas. 
 
 "Hamas will pay," said Israeli Prime Minister Benjamin Netanyahu. 
 
 Hamas spokesman Sami Abu Zuhri warned against escalation, saying that if Netanyahu "brings a war on Gaza, the gates of hell will open to him." 
 
 The three bodies were found northwest of Hebron, according to the Israeli military, which said they were still in the process of being identified. 
 
 The teens -- Eyal Yifrach, 19; Gilad Shaar, 16; and Naftali Frankel, a 16-year-old dual U.S.-Israeli citizen -- disappeared late June 12 or early June 13 from the Jewish settlement of Gush Etzion in the West Bank, the military said. 
 
 "Although the identification has not been officially confirmed, I would like to send my support and condolences to the Shaar, Frankel and Yifrach families," Maj. Gen. Nitzan Alon, with the Israel Defense Forces, told reporters.

 He vowed to pursue those responsible. 
 
 "The war on terror continues. It didn't begin now and it will not be over soon," Alon told reporters. 
 
 "We will do whatever it takes to deter Hamas and other terrorists and we'll continue to fight terror using every legal means at our disposal." 
 
 An aunt of one of the victims told CNN she was still in shock. 
 
 "I'm holding his picture and I see his smile," said Leehy Shaar, Gilad Shaar's aunt. "He's so young and innocent ... It's just too sad to even imagine." 
 
 'United in mourning' 
 
 Netanyahu called an emergency security Cabinet meeting about the issue Monday. 
 
 "All Israel tonight is united in mourning the three teens who were brutally murdered by the Hamas terrorists," said Mark Regev, a spokesman for the Prime Minister, stressing that Israel will "continue to act against Hamas in order to protect our people." 
 
 "Hamas says every Israeli man, woman and child, every civilian, is a legitimate target for these sort of terrorist attacks, so we're totally within our rights to protect ourselves against those Hamas terrorists who want to kill our people," Regev said. 
 
 When asked whether he holds the Palestinian Authority responsible in any way for the teens' deaths, he responded: "It's clear that the terrorists came from areas under Palestinian Authority control and returned to territories under Palestinian Authority control." 
 
 The spokesman urged Palestinian Authority President Mahmoud Abbas to annul his pact with Hamas. 
 
 His comments were echoed by U.S. Reps. Ileana Ros-Lehtinen, R-Florida, chairman of the House Middle East and North Africa subcommittee; and Ted Deutch, D-Florida, ranking member of that subcommittee. 
 
 "We will continue to support the government of Israel in its efforts to bring the perpetrators to justice, and we offer the people of Israel our deepest and most heartfelt condolences as we grieve with them. If it is determined that Hamas is behind this horrific tragedy, Abu Mazen must immediately break up the unity agreement between Fatah and Hamas, a U.S. designated foreign terrorist organization," they said in a statetment. 
 
 Abu Mazen is another name for Abbas, whose government now includes Hamas, which controls Gaza. 
 
 Global outcry 
 
 Abbas called an emergency meeting of his own. The Palestinian leadership is expected to meet Tuesday to discuss the developments.

 U.S. President Barack Obama, Pope Francis and U.N. Secretary-General Ban Ki-moon were among world leaders condemning the killings Monday. 
 
 "As a father, I cannot imagine the indescribable pain that the parents of these teenage boys are experiencing. The United States condemns in the strongest possible terms this senseless act of terror against innocent youth," Obama said in a statement. 
 
 He continued: "From the outset, I have offered our full support to Israel and the Palestinian Authority to find the perpetrators of this crime and bring them to justice, and I encourage Israel and the Palestinian Authority to continue working together in that effort. I also urge all parties to refrain from steps that could further destabilize the situation." 
 
 Last week, the Israel Security Agency said it believed that two "Hamas activists from Hebron" were behind the teens' disappearances. It identified them as Marwan Qawasmeh, 29, and Amar Abu-Isa, 32. 
 
 As Israeli media were reporting on the bodies' discovery Monday night, Israeli forces were blocking roads into Hebron, a city in the southern West Bank. Fighter jets could be heard flying low over Gaza. 
 
 Overnight into Tuesday, more than 40 Israeli airstrikes hit Gaza, according to Palestinian security and medical sources. The strikes targeted Hamas, Islamic Jihad and other militant groups, the sources said. 
 
 The Israeli military later said that forces had carried out strikes against 34 targets in Gaza, targeting terror infrastructure, after the firing of 18 rockets at Israel since Sunday evening. 
 
 Within days after the teens disappeared, Israeli security forces conducted an extensive search for them and detained more than 150 Palestinian suspects. 
 
 Netanyahu blamed Hamas for the kidnappings almost immediately. A Hamas spokesman said in the days after the abductions that the Prime Minister's comments attributing blame were "stupid and baseless." 
 
 Also in the days after the abductions, the mother of one of the teenagers spoke to reporters. 
 
 The three "were just on their way home," said Naftali's mother, Racheli Frankel. "We trust" that they "will be with us here, and we'll hug them soon." ||||| JERUSALEM (AP) — The Israeli military found the bodies of three missing teenagers on Monday, just over two weeks after they were abducted in the West Bank, allegedly by Hamas militants — a grisly discovery that culminated a feverish search that led to Israel's largest ground operation in the Palestinian territory in nearly a decade and raised fears of renewed fighting with Hamas.

 Israeli Prime Minister Benjamin Netanyahu vowed tough action as he convened an emergency meeting of his Security Cabinet. 
 
 "Hamas is responsible, and Hamas will pay," the Israeli leader said in a statement, adding the teenagers "were kidnapped and murdered in cold blood by human animals." In Washington, President Barack Obama urged restraint. 
 
 Eyal Yifrah, 19, Gilad Shaar, 16, and Naftali Fraenkel, a 16-year-old with dual Israeli-American citizenship, disappeared June 12 while hitchhiking home from the Jewish seminaries where they were studying near the West Bank city of Hebron. Despite the dangers, hitchhiking is common among Israelis traveling in and out of Jewish settlements in the West Bank. 
 
 Lt. Col. Peter Lerner, a military spokesman, said the bodies were found "under a pile of rocks" near the village of Halhul, just north of Hebron. 
 
 Binyamin Proper, who was among the civilian volunteers who found the bodies, told Channel 2 TV that a member of the search party "saw something suspicious on the ground, plants that looked out of place, moved them and moved some rocks and then found the bodies. We realized it was them and we called the army." 
 
 Shortly after the abductions, Israel accused Hamas of being responsible and launched a frantic manhunt throughout the West Bank, arresting nearly 400 Hamas militants. Last week, Israel identified two well-known Hamas operatives as the chief suspects. The two men remained on the run late Monday. 
 
 The search for the teens captured the nation's attention. The Israeli media delivered round-the-clock updates, and the mothers of the three teens became high-profile figures as they campaigned for their sons' return. At one point, the women addressed the U.N. Human Rights Council in Geneva to draw attention to their plight. Israelis held daily prayer vigils, including mass gatherings attended by tens of thousands of people at the Western Wall, the holiest prayer site in Judaism, and in a downtown square in Tel Aviv. 
 
 News of their deaths prompted an outpouring of grief among Israelis. Friends and neighbors rushed to the homes of the families in the Israeli towns of Nof Ayalon and Elad, and the West Bank settlement of Talmon, while supporters lit memorial candles and prayed. Large crowds gathered in Tel Aviv's central Rabin Square, and at the West Bank junction where the youths were abducted, singing songs and lighting candles shaped in the names of the youths or the Jewish Star of David. 
 
 "All of Israel bows its head today," said President Shimon Peres. 
 
 Thousands of Israelis have died in wars and militant attacks over the years, and Israel has grappled with the kidnappings of soldiers by militant groups in the past. But the ages of the victims, and the fact that they were not armed, seemed to strike a raw nerve. With Israeli soldiers ordered not to hitchhike, security officials have long feared that civilians in the West Bank could make easy targets for kidnappers. 
 
 Hamas frequently encourages its members to try to kidnap Israelis, believing hostages could be used to win the release of militants detained in Israeli prisons. Tensions had also been high since the shooting deaths in May of two Palestinian teens during a stone-throwing clash with Israeli security forces. 
 
 Netanyahu was huddling with his Security Cabinet, a group of senior government ministers, late Monday debating a response. But Israel's options could be limited. 
 
 After a two-week crackdown on Hamas in the West Bank, few major targets remain in the West Bank. Hamas had already been weakened by seven years of pressure by Israel and the forces of Palestinian President Mahmoud Abbas, and Israeli troops seemed to find very little during the latest crackdown. 
 
 Israel could turn its attention toward the Gaza Strip, where Hamas is the main power. Israel has already been battling a wave of rocket fire from Gaza that erupted in response to its West Bank operation, and it could step up the intensity of its reprisals. 
 
 Israel has not publicly provided much evidence proving Hamas involvement, and it is not clear whether the kidnappers received orders from higher-ups or acted on their own. The group praised the kidnappings, but never claimed responsibility. 
 
 In Gaza, Hamas spokesman Sami Abu Zuhri warned Israel against any broad offensive. Gaza militants possess thousands of rockets, and would almost certainly unleash heavy barrages at Israel if Israel attacks. 
 
 "Netanyahu should know that threats don't scare Hamas, and if he wages a war on Gaza, the gates of hell will open on him," he said. 
 
 Netanyahu's spokesman, Mark Regev, said Israel would step up its calls for Abbas to dissolve the unity government he recently formed with the backing of Hamas. 
 
 Abbas has condemned the kidnappings, and his forces coordinated closely with Israel during the search for the teens. But he has so far refused Israeli calls to end the unity government, which ended a seven-year rift with Hamas. The Palestinian president called an urgent meeting of the Palestinian leadership on Tuesday to discuss the events, his spokesman Nabil Abu Rdeneh said. 
 
 Abdallah Abdallah, an adviser to Abbas, said the Palestinians regretted the loss of life. 
 
 "We want peace to be created in this part of the world so no mother or no family will be bereaved for the loss of their beloved ones, Palestinian or Israeli," he said. 
 
 Abbas says his new Cabinet is committed to his political program seeking peace with Israel. Hamas is not part of his government, but has lent its backing from the outside. 
 
 The unity deal ostensibly ended seven years of Hamas rule in Gaza. But the militant group remains in firm control of the seaside territory. 
 
 In Washington, Obama condemned the killings and sent his "deepest and heartfelt condolences" to the families of the youths. "As a father, I cannot imagine the indescribable pain that the parents of these teenage boys are experiencing," he said. He also urged "all parties" to refrain from steps that could further destabilize the situation. 
 
 Pope Francis, who in May visited the region, shared in the teens' families "unspeakable pain," said the Vatican spokesman, the Rev. Federico Lombardi. In a statement, Lombardi said the "abominable and unacceptable" crime was a grave obstacle to peace and that Francis was praying that God "inspires all thoughts of compassion and peace."

– After the bodies of three kidnapped Israeli teens were found near where they were last seen in the West bank, Prime Minister Benjamin Netanyahu vowed that "Hamas will pay"—and within hours, Israeli jets and helicopters began dozens of airstrikes on the Hamas-run Gaza Strip. There were at least 34 airstrikes overnight, reports the New York Times, which calls the strikes an escalation of two weeks of skirmishes that have included the firing of rockets into Israel. More: In the West Bank city of Hebron, witnesses say the Israeli military has blown up the homes of Hamas suspects Marwan Qawasmeh and Amer Abu Eisheh, in the first punitive demolitions since Israel abandoned the practice in 2005, reports the Guardian. The two suspects disappeared shortly after the abduction. According to reports in the Israeli media, investigators believe the three teens were shot dead within minutes of being kidnapped, after one of them managed to call an emergency hotline. Their bodies were found in a field near Hebron 19 days after they disappeared. A Hamas spokesman says "no Palestinian group, Hamas or any other group," has taken responsibility for the killings. He accuses Israel of using the kidnap to justify attacks on Palestinians, and warns that if Israeli forces "carry out an escalation or a war, they will open the gates of hell on themselves," the BBC reports. One of the teens held American citizenship and President Obama has issued a statement saying "as a father, I cannot imagine the indescribable pain that the parents of these teenage boys are experiencing." He also urged "all parties to refrain from steps that could further destabilize the situation." A West Bank man shot in the chest early today has become the sixth Palestinian to be killed by the Israeli military since the teenagers' disappearance sparked a huge crackdown, reports CNN.
