US-backed forces in Syria announced Thursday that they have captured nearly half of ISIS' de facto capital of Raqqa, Associated Press reported.

The Syrian Democratic Forces - largely made up of Kurdish, Sunni and Christian fighters - began their assault on Raqqa on June 6, and have since taken about 45% of the city, according to Army Col. Ryan Dillon, a spokesman for Operation Inherent Resolve.

Still, US-backed forces have faced "stiff, sporadic resistance" resistance from ISIS militants, Dillon said.
