Air strikes by U.S.-led forces in Syria have killed 910 people, including 52 civilians, since the start of the campaign against Islamic State and other fighters two months ago, a group monitoring the conflict said on Saturday.

The majority of the deaths, 785, were Islamic State fighters according to the Britain-based Syrian Observatory for Human Rights. Islamic State, a hard-line offshoot of al Qaeda, has seized land in Syria and neighboring Iraq, where it has also been targeted by U.S.-led strikes since July.
