US-led coalition airstrikes pound Islamic State stronghold in Syria

Syrian activists say the US-led coalition has carried out as many as 30 airstrikes against Islamic State militants in and around the group’s de facto capital in northeastern Syria.

The Britain-based Syrian Observatory for Human Rights said Sunday that the strikes took place overnight and targeted IS positions in the city of Raqqa as well as the Division 17 air base, which the militants seized earlier this year from government forces.

The monitoring group, which relies on a network of activists inside Syria, reported at least 30 coalition strikes in all. The Local Coordination Committees, an activist collective, also confirmed the airstrikes. Neither group had casualty figures.
