 Israel's foreign minister and Hamas have denied earlier reports of a truce deal to end fighting in Gaza between Israel and Palestinian militants. 
 
 Avigdor Lieberman said the reports were "as of now incorrect", and Hamas, which controls Gaza, said talks in Egypt were ongoing. 
 
 An Israeli official earlier told the BBC the truce was to take effect on Friday at 06:00 local time (03:00 GMT). 
 
 Some 227 Palestinians and one Israeli have died in nine days of conflict. 
 
 Israel launched its Operation Protective Edge with the stated objective of halting Palestinian rocket attacks on Israel. 
 
 However, the United Nations says most of those killed in Gaza have been civilians. 
 
 Israel accuses Hamas of hiding its military infrastructure within the civilian population.

 On Thursday, the UN Relief and Works Agency for Palestine refugees said it had found 20 rockets hidden in one of its vacant schools in Gaza and "strongly condemned" whichever group had placed them there. 
 
 A five-hour humanitarian ceasefire took place on Thursday but hostilities quickly resumed after it ended. 
 
 'Intensive talks' 
 
 Egypt has been mediating in negotiations between Israel and Hamas. 
 
 Earlier reports said a new truce deal had been agreed by Israeli negotiators but that it had not yet been approved by the Israeli cabinet. 
 
 Analysis: BBC's Kevin Connolly in Jerusalem 
 
 In an off-the-record briefing in some of Thursday morning's overseas newspapers a senior Israeli military official is quoted as describing the likelihood of an Israeli ground operation in Gaza as "very high". The military logic is clear, as it always has been. 
 
 Israel's air force is steadily working its way down a long target list. But there are other targets that could only be reached by ground forces - better-concealed long-range rockets are one example. 
 
 Ground operations could mean anything from raids by units of Israel's Special Forces to an all-out invasion and occupation. That would mean Israeli casualties too - perhaps a lot of them - and give Israel responsibility for running Gaza even as it hunted and fought militants. 
 
 Lots of Israeli politicians want the army to go in, but so far PM Benjamin Netanyahu is hesitating. In the meantime, leaks suggesting a ground operation is "highly likely" are a psychological weapon in themselves. 
 
 However, Hamas spokesman in Gaza Sami Abu Zuhri told Agence France-Presse: "The news about a ceasefire is incorrect. There are continuing efforts but no agreement until now." 
 
 Mr Lieberman told Israeli media: "The reports of a ceasefire are far from representing reality. I spoke with the prime minister, and as of now they are incorrect."

 A spokesman for Islamic Jihad, which is also involved in the talks, told the BBC the discussions in Cairo were "ongoing and intensive" and that Hamas and Islamic Jihad had asked for amendments to the Egyptian initiative, which the mediators were dealing with "positively". 
 
 Stocking up 
 
 The humanitarian truce took place between 10:00 and 15:00 local time on Thursday. 
 
 It was requested by the UN and other international organisations to provide emergency relief and distribute water, food and hygiene kits. 
 
 Gazans used the truce to stock up on supplies. They queued outside banks and there were traffic jams. 
 
 Both sides reported violations of the temporary truce. 
 
 And a few minutes after it ended, the Israel Defense Forces said a rocket fired from Gaza had hit the town of Ashkelon. It was followed by reports of further rocket attacks. 
 
 Witnesses in Gaza reported Israel's first air strike since the temporary truce ended - on agricultural land near Beit Lahiya. 
 
 The health ministry in Gaza later said an Israeli air strike had hit a home in Gaza City, killing three children. 
 
 Fighting had continued until the temporary truce came into effect on Thursday morning.

 Palestinian medics said three people were killed by Israeli tank fire which hit a house in Rafah minutes before the ceasefire began. 
 
 The Israeli military earlier confirmed it had carried out dozens of air strikes on targets in Gaza since midnight, while Palestinian militants continued to fire rockets at Israeli cities. 
 
 The Israeli military also said it had thwarted the infiltration into Israel by 13 Hamas gunmen via a tunnel from southern Gaza towards the southern Israeli kibbutz of Sufa on Thursday morning. 
 
 Killings 'unintentional' 
 
 Meanwhile, Israeli President Shimon Peres has apologised for the deaths of four Palestinian children killed when Israeli artillery fire hit a beach near Gaza City on Wednesday.

 "I think it was unintentional and we are really sorry to see four children being killed," he said in an interview with the BBC. 
 
 He said an evacuation warning had been issued ahead of the air strike, which was targeting "a great concentration of weapons" in the area. 
 
 The Israeli military said it was "carefully investigating" the incident, adding that "based on preliminary results, the target of this strike was Hamas terrorist operatives". 
 
 Israel says it has carried out more than 1,960 attacks on Gaza since 8 July, while militants have fired some 1,380 rockets at Israel. 
 
 The Israeli military has mobilised tens of thousands of troops on the border with Gaza amid speculation that a ground invasion could be launched. 
 
 The UN says at least 1,370 homes have been destroyed in Gaza and more than 18,000 people displaced in recent hostilities. ||||| Image copyright Reuters Image caption Photos have emerged purporting to show the aftermath of a strike on Gaza City after the truce began 
 
 Israel's "humanitarian window" for parts of Gaza has ended, having slowed violence over its seven-hour period. 
 
 Israel had said the truce would not apply to Rafah in the south and its troops would respond if attacked. 
 
 Palestinian officials said Israel broke the truce shortly after it began, hitting a house in Gaza City. 
 
 In Jerusalem, Israeli police said a Palestinian construction vehicle driver was shot dead after an attack on a bus that killed an Israeli passer-by. 
 
 Israeli media later said one person - reportedly a soldier - had been seriously injured in a suspected drive-by shooting in Jerusalem's Mt Scopus area. 
 
 As the truce ended, Israeli PM Benjamin Netanyahu issued a statement vowing to continue operations in Gaza until calm was restored. 
 
 Tunnels 
 
 The truce followed an attack near a UN-run school in Gaza on Sunday that sparked international outrage. Palestinian officials said at least 10 people died. 
 
 Earlier, the Israel Defense Forces (IDF) confirmed that they had begun withdrawing some troops from Gaza, saying they were "extremely close" to completing their mission to destroy a network of tunnels. 
 
 Health officials in Gaza say 1,800 Palestinians, most of them civilians, have been killed and more than 9,000 injured since the conflict began nearly four weeks ago. 
 
 Sixty-seven Israelis have died, all but three of them soldiers. A Thai national working in Israel was also killed.

 Martin Patience, BBC News, Gaza 
 
 Previous ceasefires and truces have all come and gone in Gaza. Most have crumbled within a matter of hours. And while Israel has announced a "humanitarian window", nobody here has any faith in it. 
 
 Israel says that it will continue its military operations close to the southern town of Rafah. Just minutes after the ceasefire got under way, Palestinians say Israel carried out in airstrike inside Gaza city - an area that was supposed to be covered by the truce. 
 
 We heard the explosion at our Gaza bureau. A BBC team saw a house that had been destroyed - locals say that at least one person died and others were injured in the attack. There's yet to be any word from the Israeli military. But it's for this reason that Palestinians say that no place in Gaza is safe - ceasefire or not. 
 
 Bethany Bell, BBC News, Jerusalem 
 
 The news that the Israeli army has redeployed some of its troops along the Gaza border and announced a partial humanitarian ceasefire for a few hours, has prompted some speculation that it may be trying to wind down the military operation unilaterally, without an agreed ceasefire with Hamas. 
 
 But it is by no means clear that an end to the fighting is in sight. The offensive around Rafah, near the Egyptian border, continues, possibly to try to make it harder for Hamas to re-arm in future. And the army may be searching for more cross border tunnels that it has not yet identified. 
 
 There is intense international pressure on Israel to negotiate a long-term ceasefire. For now, Israel appears to be ignoring those calls, but it hasn't ruled out a possible diplomatic solution.

 Violation of truce? 
 
 Hamas responded to the truce with suspicion, accusing the IDF of trying to "divert the attention from Israeli massacres". 
 
 Palestinian health officials said Israel carried out an air strike on a refugee camp inside Gaza City just minutes after the ceasefire began. 
 
 BBC correspondents there said they heard the explosion and saw a house that had been destroyed in the attack. 
 
 Reports suggest the strike killed a young girl and injured at least 15 others, many of them women and children.

 Israel's temporary ceasefire - aimed at allowing Palestinians to return to their homes - did not include Rafah because there was an "Israeli military presence" there and "clashes were still ongoing", the IDF said. 
 
 The truce began at 10:00 local time (07:00 GMT) and ended at 17:00 (14:00 GMT). 
 
 In attacks before the truce came into effect, an Islamic Jihad commander in northern Gaza, Daniel Mansour, was killed when his home was hit. 
 
 In Jerusalem, a construction vehicle driven by a man, identified by police as a Palestinian from east Jerusalem, overturned a bus in an ultra-Orthodox neighbourhood. 
 
 A passer-by was killed and several people were injured before police shot dead the driver. 
 
 Israeli media also reported that dozens of rockets had been fired from Gaza on Monday. 
 
 'Disgraceful shelling' 
 
 More than a quarter of the 1.8 million residents in the Palestinian territory have been displaced in the most recent hostilities. 
 
 Many of those who have fled their homes have taken refuge in UN shelters across Gaza, including the UN-run school in Rafah which was hit on Sunday. 
 
 The IDF said it had targeted three Islamist militants near the school. 
 
 UN chief Ban Ki-moon described the Israeli strike as "a criminal act" and the US said it was appalled by the "disgraceful shelling". 
 
 Mr Netanyahu said Israel was "sorry for any attack that unintentionally hits civilians", but accused Hamas of turning UN facilities into "terrorist hotspots". 
 
 The IDF says 2,560 rockets and mortars fired from Gaza have landed in Israel since 8 July, and that its Iron Dome defence system has intercepted another 556 rockets.

 International efforts to finalise a ceasefire are being stepped up after a night of renewed Israeli air strikes in Gaza and sporadic Hamas rocket attacks. 
 
 US Secretary of State Hillary Clinton is visiting the West Bank and, later, Cairo after talks with Israeli leaders. 
 
 Palestinian sources had suggested a truce would be announced on Tuesday, but Israel said no deal was struck. 
 
 Some 136 Palestinians and five Israelis have been killed since the flare-up began eight days ago, officials say. 
 
 On Tuesday alone, the conflict claimed the lives of at least 20 Palestinians and two Israelis. 
 
 Mrs Clinton has arrived in Ramallah on the West Bank for talks with Palestinian Authority President Mahmoud Abbas. UN Secretary General Ban Ki-moon is also visiting leaders in the region to try to cement a ceasefire. 
 
 In Cairo, officials from Hamas, the militant Palestinian group that has governed Gaza since 2007, had suggested a truce would come into effect at midnight on Tuesday, but Israel later said it had not agreed to a text. 
 
 Israel's demands include no hostile fire of any kind from Gaza and international efforts to prevent Hamas from re-arming, while Hamas is demanding an end to the blockade on Gaza and targeted killings by Israel.

 An Israeli official told Israel Radio the ceasefire had not been agreed because of "a last-minute delay in the understandings between Hamas and Israel". 
 
 Offices struck 
 
 In the early hours of Wednesday, BBC correspondents in Gaza reported hearing loud explosions that were followed by a widespread power cut. 
 
 Israeli missiles struck the main complex of the Hamas-run government in the centre of Gaza City. 
 
 The BBC's Paul Danahar in Gaza said the huge compound had been laid to waste and was little more than dust and rubble. 
 
 The Israeli military later tweeted it had "surgically targeted a Hamas intelligence operations centre" on the seventh floor of a media building. 
 
 Israel's military, the Israel Defense Forces (IDF), said it had attacked more than 100 "terror sites" in Gaza overnight "of which approximately 50 were underground rocket launchers". 
 
 The health ministry in Gaza said 15 more people had been injured overnight. 
 
 The BBC's Jon Donnison in Gaza says the streets were again empty on Wednesday morning, as people tried to protect themselves at home while waiting for something positive to come from talks in Cairo. 
 
 Israel says more than 800 rockets have been fired from Gaza into Israel over the past week, 162 in the past day alone. 
 
 Many of the rockets have been intercepted by Israel's Iron Dome missile defence system. 
 
 Overnight, two rockets were knocked down by Iron Dome and others landed on open ground, Israel Radio said. By morning, air raid sirens sounded in many parts of southern Israel, local media reported. 
 
 'Sustainable outcome' 
 
 Hamas officials in Cairo accused Israel of failing to respond to ceasefire proposals. 
 
 Israeli spokesman Mark Regev told the BBC: "I have no doubt that Hamas would be more than happy to have a temporary respite - a time out... so they could rest and re-arm and we would have missiles on Israel next week or next month. We are not interested in that."

 US state department spokeswoman Victoria Nuland said Mrs Clinton - who flew into Jerusalem late on Tuesday - had held two hours of talks with Israeli Prime Minister Benjamin Netanyahu and other Israeli officials. 
 
 "They discussed efforts to de-escalate the situation and bring about a sustainable outcome that protects Israel's security and improves the lives of civilians in Gaza," Ms Nuland said. 
 
 Speaking just before the talks, Mr Netanyahu said Israel wanted a diplomatic solution but that he was ready to take "whatever action" was necessary. 
 
 "If there is a possibility of achieving a long-term solution to this problem by diplomatic means, we prefer that. But if not, then I am sure you will understand that Israel will have to take whatever actions are necessary to defend its people," he said. 
 
 Israel's Haaretz newspaper said there were divided views in the government over the truce proposals, with Defence Minister Ehud Barak in favour of accepting an Egyptian draft, while Mr Netanyahu and Foreign Minister Avigdor Lieberman were opposed. 
 
 The BBC's Jon Leyne in Cairo says both sides want more out of this than just a ceasefire. The Palestinians want a lifting of the blockade of Gaza, permanently reopening the borders. He says the hope would be that this will defuse tension and reduce pressure on Hamas. 
 
 The Israelis want an end to attacks, our correspondent says, but specifically want to prevent Hamas restocking its missiles. He says the key to that is how the Egyptians can seal the border; but this is politically sensitive among the Egyptian people and also physically difficult, as the military has a lot of trouble controlling militants in Sinai. 
 
 Israel launched its current offensive a week ago with the killing of Hamas military leader Ahmed Jabari. The Israeli government says his assassination, and the subsequent offensive, aims to end rocket fire from Gaza. 
 
 Israel has troops massed along the Gaza border but says it is holding off on a possible ground invasion as talks continue.
– The temporary Gaza ceasefire was broken today when three rockets landed in Israel, its military says, per the AP; the reported attack prompted new Israeli airstrikes within minutes. The rockets landed in fields near Beersheba, southern Israel; no one was hurt, officials say. An Israeli official says the military's new strikes are targeting "terror sites," the BBC reports. The attacks came hours before the scheduled end of the current ceasefire, the New York Times notes, adding that it's not certain who was behind the latest rocket attacks.
