Drone video shows devastation in Raqqa, Syria

Drone footage from the northern Syrian city of Raqqa shows the extent of devastation caused by weeks of fighting between Kurdish-led forces and the Islamic State group.

Footage from Thursday shows the bombed-out shells of buildings and heaps of concrete slabs lay piled on streets littered with destroyed cars.

Entire neighborhoods are seen turned to rubble, with little sign of civilian life.

The U.S.-backed Kurdish-led Syrian Democratic Forces announced they have driven Islamic State group militants out of the city after weeks of fighting.

The spokesman for the coalition, Col. Ryan Dillon, tweeted on Thursday that the SDF has cleared 98 percent of the city, adding that some militants remain holed up in a small pocket east of the city's athletic stadium.
