A commander with the U.S.-backed Syrian forces battling the Islamic State says the city of Raqqa has been liberated from ISIS militants and combing operations are underway to clear the city of landmines and extremist sleeper cells.
Brig. Gen. Talal Sillo told The Associated Press on Tuesday that there are no longer clashes going on in the city.
Sillo says a formal declaration will follow befitting “the fall of the capital of terrorism.”
Dozens of militants who refused to surrender had made their last stand in the city’s stadium, which had become notorious as a prison and dungeons for the group.
It wasn’t immediately clear if the IS militants are still holed up inside the stadium.
The city of Raqqa fell to the Islamic State group in 2014 and became the de facto capital of their self-styled caliphate.

Losing Raqqa has been a huge blow for the militant group, which has steadily lost territory in Iraq and Syria, including Iraq’s second largest city of Mosul a few months ago. The group declared the city on the banks of the Euphrates River, which it seized from other Syrian rebels in early 2014, to be the capital of its self-styled “caliphate,” transforming the one vibrant metropolis into the epicentre of its brutal rule where opponents were beheaded and terror plots were planned.
On Monday, the Kurdish-led SDF captured “Paradise Square,” Raqqa’s infamous public square where Islamic State militants used to perform killings and beheadings, forcing residents to watch after summoning them with loudspeakers.
Bodies and severed heads would linger there for days, mounted on posts. Residents described how the bodies of those slain would be labelled, each with his or her perceived crime, for the public to see.

The square previously known for its famous ice cream shop was quickly renamed from Paradise to Hell Square, Jahim in Arabic.
The Kurdish-run Hawar news agency said with the capture of the hospital, the last black ISIS flag raised in the city had been taken down. A video released by the news agency illustrated the clashes around the hospital building, which appeared riddled with bullets and partly blackened from a fire.
The battle for Raqqa began in June and has dragged for weeks as the Syrian fighters faced stiff resistance from the militants.
In the campaign, the city suffered major devastation, leaving most of its building levelled and in ruins.
