BEIRUT (AP) — U.S.-backed Syrian forces were removing land mines and clearing roads in the northern city of Raqqa on Wednesday, a day after commanders said they had driven the Islamic State group from its de facto capital.
Mustafa Bali, spokesman for the Kurdish-led Syrian Democratic Forces, said preparations were underway for a formal declaration of the city's liberation.
The SDF said Tuesday that military operations in Raqqa have ended and that their troops have taken full control of the city. The U.S.-led coalition cautioned that the clearing operations would continue, saying some 100 militants may still be hiding in the city.
On Wednesday, the spokesman for the coalition, Col. Ryan Dillon, tweeted that 95 percent of the city is now under full control as clearing operations continue.
The coalition stressed that the SDF has been successful in holding onto captured territory because of its thorough clearing procedures, which prevent counterattacks.
Brett McGurk, the top U.S. envoy for the coalition, said he was in northern Syria to prepare for the defeat of the militants. He said the United States will help in clearing explosives as well as restoring services in the city.
McGurk posted a photograph Wednesday of surrendering IS militants, saying: "Once purported as fierce, now pathetic and a lost cause." He said IS lost nearly 6,000 militants in Raqqa before surrendering in large numbers.
The White House said the imminent liberation of the Islamic State stronghold of Raqqa will open a new phase in the Syrian conflict. Spokeswoman Sarah Huckabee Sanders blamed the Syrian government for hindering previous efforts to free Raqqa.
U.N. Secretary-General Antonio Guterres said the latest developments in Syria "point once again to the urgent need to reinvigorate the political process," according to U.N. spokesman Stephane Dujarric. He said Guterres had directed the U.N. special envoy for Syria, Staffan de Mistura, to intensify efforts to reconvene the next round of peace talks between the government and opposition.
Aid and charity organizations have warned of the high cost borne by civilians.
In the neighboring Deir el-Zour province, where the SDF and Russian-backed Syrian troops are waging separate offensives against the militants, nearly half a million civilians remain trapped by the fighting, the International Rescue Committee said late Tuesday.
The U.N. refugee agency said that in the last few days, around 40,000 Raqqa residents arrived in already overcrowded displacement camps in the province, warning of the danger of land mines and unexploded ordnance.
The fall of Raqqa marks a major defeat for the extremist group, which has seen its self-styled Islamic caliphate steadily shrink since summer. IS took over Raqqa, located on the Euphrates River, in 2014 and transformed it into the epicenter of its brutal rule.
The group still holds territory to the south of Raqqa and in Deir el-Zour, as well as smaller pockets elsewhere in Syria and Iraq.
On Wednesday, fierce clashes were reported between the SDF and IS militants in the group's last strip of land in Hassakeh province, to the east of Raqqa. The Syrian Observatory for Human Rights also reported intense clashes between forces allied with the Syrian government and IS militants.
A media outlet affiliated with the Syrian military said a senior commander who led the fight against IS in Deir el-Zour was killed Wednesday in operations against the group.
The Central Military Media described Brig. Gen. Issam Zahreddine, 56, as one of the most important field commanders in the Syrian army, saying he was instrumental in breaking a nearly three-year IS siege on the city of Deir el-Zour earlier this year. The Lebanese Al-Manar TV, which is close to the Syrian government, said a land mine killed him.
Zahreddine maintained a government presence in Deir el-Zour despite the prolonged siege on his forces. The siege was breached in September in a Russian-backed offensive, and the government and allied troops have since retaken most of the city.
Zahreddine also led government offensives against armed opposition in the central Homs province and near the capital, Damascus, in the earlier days of the Syrian conflict.
In comments widely played after Deir el-Zour's siege was breached, Zahreddine warned those who fled the country not to return because the army "will never forget or forgive." He later apologized on state TV.
