An Iraqi military spokesman says reinforcements have been dispatched to Ramadi, a city now largely held by the Islamic State group.

The spokesman of the Joint Operations Command, Brig. Gen. Saad Maan Ibrahim, told Iraqi state television Saturday that the U.S.-led coalition was supporting Iraqi troops with "painful" airstrikes since late Friday.

Ibrhaim didn't give details on the ongoing battles, but vowed that the Islamic State group would be pushed out of the city "in the coming hours."

On Friday, the militants swept through Ramadi, the capital of Anbar province, seizing the main government headquarters and other key parts of the city. The gains marked a significant setback for the Iraqi government in its long fight to dislodge militants, who hold about a third of the country.
