ISIS has finally been defeated in Raqqa

U.S.-backed Syrian forces liberated the city of  on Oct. 17 from Islamic State militants, a senior commander said, in a major defeat for the collapsing extremist group that had proclaimed it to be the capital of its “caliphate.”

Although clashes in  have ended, the Kurdish-led Syrian Democratic Forces are in control, combing the city in northern Syria for land mines and searching for any IS sleeper cells, Brig. Gen. Talal Sillo told The Associated Press.

Sillo said a formal declaration that  has fallen would be made soon, once troops finish their clearing operations in the city on the banks of the Euphrates River.

Col. Ryan Dillon, a spokesman for the U.S.-led coalition, said it has not yet received official reports that the city was cleared, describing mines and booby traps throughout  that have killed returning civilians and senior Syrian Democratic Forces (SDF) commanders in recent days. One of those killed Oct. 16 was the head of the internal security force affiliated with the SDF.

Another challenge for the troops is searching the tunnels that were dug by the militants around the city, Dillon said.

“This will take some time, to say that the city is completely clear,” he told AP. “We still suspect that there are still (IS) fighters that are within the city in small pockets.”

The loss of  will deprive the militants of a major hub for recruitment and planning, Dillon said, because the city attracted hundreds of foreign fighters and was a place where attacks in the Middle East and Europe were planned. He added that the militants remain active in Syria, farther south around the eastern province of Deir el-Zour.

“This has been the wellspring of (IS) as we know it,” he said. But he stressed that the military defeat of the militants “doesn’t mean the end of (IS) and their ideology.”

Dozens of militants who refused to surrender made their last stand earlier Oct. 17 in  sports stadium, which the group had turned into a notorious prison in the more than three years it held the city.

The SDF forces earlier captured  main hospital, the other last remaining IS holdout that had served both as a medical facility and an IS command center. The SDF fighters have not gone through it to clear it, Dillon said.

Dillon said the coalition has not carried out any airstrikes in the past three days to allow civilians to leave. The SDF has also called on IS fighters to surrender, and about 350 have turned themselves in, he said, adding that none were high-value targets.

In recent months, the Islamic State has steadily lost territory in Iraq and Syria, including Iraq’s second-largest city of Mosul.

After the group seized  from other Syrian rebels in early 2014, it transformed the one vibrant metropolis into the epicenter of its brutal rule where opponents were beheaded and terror plots hatched.

IS militants had been cornered in and around the stadium, and it was not immediately clear after Sillo’s statement whether any were still inside it.

“The stadium is a huge structure with underground rooms and tunnels. There are also buildings around it” still under the control of IS, said SDF spokesman Mustafa Bali.

A senior Kurdish commander said later that the stadium has been checked and cleared of land mines. SDF forces raised their own flag in the stadium, he added.

Earlier, he said 22 IS militants were killed in the advance on the hospital.

On Oct. 17, the SDF captured “Paradise Square,”  infamous public square that was used by the militants to perform beheadings and other killings in front of residents who were summoned by loudspeakers and forced to watch. Bodies and severed heads would be displayed there for days, mounted on posts and labeled with their crimes, according to residents, who later dubbed it “Hell Square.”

With the capture of the hospital, the last black IS flag was taken down, according to the Kurdish-run Hawar news agency. A video released by the news agency showed the clashes around the hospital, which appeared riddled with bullets and partly blackened from a fire.

A senior Kurdish commander said there was no sign of civilians in the stadium or around it, but he added that his troops were being cautious because of possible land mines. He spoke on condition of anonymity because he was not authorized to talk to reporters.

The battle for  began in June and has dragged for weeks as the SDF fighters faced stiff resistance from the militants. The city suffered devastating damage, with most of its buildings leveled or in ruins. The Syrian Observatory for Human Rights said more than 1,000 civilians were killed in the campaign.
