 Iraqi officials say the army is now in "full control" of central Ramadi, where so-called Islamic State (IS) has been resisting an army offensive. 
  
 A former government compound, where IS fighters had been holding out, has been retaken, Iraqi security sources say. 
  
 However there were still "pockets of resistance" in parts of the city, the provincial governor's spokesman said. 
  
 Ramadi, about 55 miles (90km) west of Baghdad, fell to IS in May, in an embarrassing defeat for the army. 
  
 Iraqi government forces, backed by coalition air strikes, has been trying to retake the mainly Sunni Arab city for weeks.

 "We believe that we do have full control of the centre of Ramadi," Muhannad Haimour, spokesman for the Anbar governor, told the BBC. 
  
 "But we're being very careful in declaring victory until we have an official announcement from the prime minister's office." 
  
 Mr Haimour said that would mean that area had been cleared of explosives, adding that officials now believed that IS militants were not "capable of launching any attacks on the security forces". 
  
 The spokesman described the remaining pockets of resistance as "very weak". 
  
 In recent days, troops have been picking their way through booby-trapped streets and buildings as they pushed towards the city centre, seizing several districts on the way. 
  
 Iraqi soldiers moved in to retake the former government compound on Sunday after sniper fire stopped and aerial surveillance detected no human activity. 
  
 An Anbar security source told the BBC on Monday that Iraqi forces had taken over the complex completely, finding "nothing but rubble and earth mounds, as most of its buildings were blown up" by IS. 
  
 The source said it might still be a few days before "full liberation" of the city is declared.

 Controlling this compound is key to retaking Ramadi. Iraqi soldiers are slowly clearing it as they fear it may have been rigged to explode. 
  
 Troops are also busy in the surrounding neighbourhood, where pockets of resistance remain. 
  
 The authorities will hail this week's offensive as a success - in stark contrast with the security forces' hasty retreat from Ramadi last May. 
  
 However, it took months to mount this ground campaign, in co-ordination with coalition air strikes. 
  
 There had been no clear indications of the number of IS militants who had been defending the city, although some reports put it at about 400. No official toll of Iraqi army casualties has been given. 
  
 The Iraqi military believes the remaining militants have headed north-east. Fighting is also reported south-west of the compound. 
  
 Concern remains for hundreds of families trapped on the frontline. Although the situation on the ground remains unclear, AFP news agency reported celebrations on the streets of a number of Iraqi cities. 
  
 The operation to recapture Ramadi began in early November, but made slow progress, mainly because the government chose not to use the powerful Shia-dominated paramilitary force that helped it regain the northern city of Tikrit, to avoid increasing sectarian tensions. ||||| BAGHDAD (AP) — Islamic State fighters are putting up a tough fight in the militant-held city of Ramadi, slowing down the advance of Iraqi forces, a senior Iraqi commander said Sunday.

 Iraq launched the long-awaited operation to retake the Anbar provincial capital, which was captured by IS militants in May, but after an initial push across the Euphrates River, their progress stalled. 
  
 Gen. Ismail al-Mahlawi, head of the Anbar military operations, told The Associated Press that the advance was hampered by suicide bombers, snipers and booby traps. 
  
 Iraqi troops will "need days" to get to the city's central government complex, said al-Mahlawi, adding that the troops were about one kilometer (half mile) from the complex on Sunday. 
  
 Al-Mahlawi said he could neither confirm nor deny media reports that IS fighters had pulled out of the government complex by nightfall Sunday. But he cited residents in the area as telling his troops that the IS militants had withdrawn from the neighborhood of Albu Alwan, adjacent to the complex. 
  
 Another officer said the Iraqi army has yet to gain full control of a single Ramadi neighborhood. He spoke on condition of anonymity because he was not authorized to talk to reporters. 
  
 On Tuesday, Iraqi security forces reported progress in recapturing some areas in the western city of Ramadi, 130 kilometers (80 miles) west of Baghdad, from IS militants. 
  
 The extremists control large swaths of land in western and northern Iraq and in neighboring Syria. The IS group has declared a self-styled caliphate on the territory under its control. 
  
 After overrunning Ramadi, IS destroyed all the bridges around the city. It also demolished the Anbar operations command center and fanned out into the city's residential areas to set up less conspicuous centers of command. 
  
 A statement late Sunday from the Iraqi joint command said the operation in Anbar is going according to plans and that Iraqi forces continue to encircle the government complex in Ramadi. It made no mention of any pullout of IS militants from the area. ||||| BAGHDAD (Reuters) - A triumphant Iraqi Prime Minister Haider al-Abadi declared on Monday that the coming year would see his forces defeat Islamic State, after his military achieved its first major victory since collapsing in the face of the fighters 18 months ago. 
  
 Iraqi forces flew the national flag above the main government complex in Ramadi earlier in the day, declaring they had recaptured the city, a provincial capital west of Baghdad, which fell to Islamic State in May. 
  
 “2016 will be the year of the big and final victory, when Daesh’s presence in Iraq will be terminated,” Abadi said in a speech broadcast on state television, using an Arabic acronym for Islamic State that the hardline group rejects. 
  
 “We are coming to liberate Mosul and it will be the fatal and final blow to Daesh,” he added. Mosul, northern Iraq’s main city, is by far the largest population center in the self-proclaimed caliphate Islamic State rules in Iraq and Syria. 
  
 The army’s apparent capture of Ramadi, capital of Anbar province in the Euphrates River valley west of Baghdad, marks a major milestone for U.S.-trained forces who crumbled when Islamic State fighters charged into Iraq in June 2014. In previous battles since then, Iraq’s armed forces operated mainly in a supporting role beside Iranian-backed Shi’ite militias. 
  
 Soldiers were shown on state television on Monday publicly slaughtering a sheep in an act of celebration. 
  
 Gunshots and an explosion could be heard as a state TV reporter interviewed other soldiers celebrating the victory with their automatic weapons held in the air. 
  
 U.S. President Barack Obama, vacationing in Hawaii with his family, received an update on Monday on the Iraqi forces’ progress in Ramadi, the White House said. 
  
 “The continued progress of the Iraqi Security Forces in the fight to retake Ramadi is a testament to their courage and determination, and our shared commitment to push ISIL out of its safe-havens,” the White House said in a statement, using an acronym for Islamic State. 
  
 Congratulating the Iraqi government, U.S. Defense Secretary Ash Carter said: “The expulsion of ISIL by Iraqi security forces ... is a significant step forward in the campaign to defeat this barbaric group.” 
  
 In a statement, Carter added: “Now it’s important for the Iraqi government ... to seize this opportunity to maintain the peace in Ramadi, prevent the return of ISIL and other extremists, and facilitate the return of Ramadi’s citizens back to the city.” 
  
 ‎ American officials said the U.S.-led coalition backing Iraqi forces had carried out more than 630 air strikes in the area over the past six months and provided training and equipment. 
  
 The U.S.-led coalition, which includes major European and Arab powers, has been waging an air campaign against Islamic State positions in both Iraq and Syria since a third of Iraqi territory fell to the fighters in mid-2014. 
  
 The Iraqi army was humiliated in that advance, abandoning city after city and leaving fleets of American armored vehicles and other weapons in the militants’ hands. One of the main challenges of the conflict since then has been rebuilding Iraq’s army into a force capable of capturing and holding territory. 
  
 Baghdad has said for months it would prove its forces’ rebuilt capability by rolling back militant advances in Anbar, a mainly Sunni province encompassing the fertile Euphrates River valley from Baghdad’s outskirts to the Syrian border. 
  
 After encircling the provincial capital for weeks, Iraqi forces launched an assault to retake it last week and made a final push to seize the central administration complex on Sunday. Their progress had been slowed by explosives planted in streets and booby-trapped buildings.

 Security officials said the forces still needed to clear pockets of insurgents in the city and its outskirts. 
  
 KEEPING CONTROL 
  
 Authorities gave no immediate death toll from the battle for the city. They have said most residents were evacuated before the assault. 
  
 Finance Minister Hoshiyar Zebari told Reuters the capture of Ramadi was “a done deal,” but said the government had to do more to rebuild the city and encourage displaced people to return. 
  
 “The most important thing is to secure it (Ramadi) because Daesh can bounce back,” he said in an interview in Baghdad. 
  
 Iraq’s army took the lead in the battle for Ramadi, with the Shi’ite militias prominent in other campaigns held back from the battlefield to avoid antagonizing the mainly Sunni population. Washington had also expressed reluctance about being seen as fighting alongside the Iranian-backed groups. 
  
 Abadi took office in September 2014 after the Islamic State advance, pledging to reconcile Iraq’s warring sectarian communities. While he initially swung behind Shi’ite militias to help halt Islamic State’s onslaught, he has since tried to implement reforms to reduce the power of sectarian parties, angering many political leaders. 
  
 Members of Islamic State, also known by the acronym ISIS, are ultra-hardline Sunnis who consider all Shi’ite Muslims to be apostates. They swept through northern and western Iraq in June 2014 and declared a “caliphate” to rule over all Muslims from territory in both Iraq and Syria, carrying out mass killings and imposing a draconian form of Sunni Islam. 
  
 The battle against the group in both Syria and Iraq has since drawn in most global and regional powers, often with competing allies on the ground in multi-sided civil wars.

 Abadi’s government plans to hand over Ramadi to local police and a Sunni tribal force once it is secured, to encourage Sunnis to resist Islamic State. 
  
 Such a strategy would echo the U.S. military’s “surge” campaign of 2006-2007, which relied on recruiting and arming Sunni tribal fighters against a precursor of Islamic State. Anbar, including Ramadi, was a major focus of that campaign at the height of the 2003-2011 U.S. war in Iraq. |||||
Output:
Iraqi forces have reclaimed the central government compound in the city of Ramadi from ISIS, marking what a US commander says is the greatest achievement yet from a force that fled the city in May. The military says it's now in complete control of the compound, which marks the defeat of ISIS in Ramadi, capital of Anbar province, though there are still pockets of resistance, reports the BBC. "Yes, the city of Ramadi has been liberated," says a military spokesman, per Reuters. The Iraqi flag is now flying over the compound, he adds. Fierce fighting had taken place around the city for days, though suicide bombers, snipers, and booby traps had slowed the Iraqi military's advance, reports AP. Col. Steve Warren, spokesman for the US anti-ISIS effort, tells USA Today that it has been a great day for the Iraqi military. "What this shows is that the Iraqis have moved from an army that folded on initial contact in the summer of '14 to an army that has been able to conduct a complex operation in a large, built-up area," he says. "This is the biggest thing the Iraqi army has done. Period." He says ISIS is now "getting hit in multiple places simultaneously," having also lost control of the Tishrin Dam in Syria to US-backed fighters over the weekend, who cut off a key supply line to the group's Raqqa stronghold when they seized the Euphrates River dam. (ISIS is believed to be harvesting organs from live prisoners for profit.)
