U.S.-led coalition airstrikes against the so-called Islamic State group and other extremists in Syria have killed more than 860 people, including civilians, since they began in mid-September.

The group said the vast majority of those killed _ 746 people _ were ISIS militants, while another 68 were members of al-Qaida's Syrian affiliate known as the Nusra Front.

At least 50 civilians, including eight children and five women, also have been killed in the airstrikes, the group said.

The U.S. Central Command said the U.S. and allied nations conducted 16 airstrikes in Syria and seven in Iraq since Monday. Most of those airstrikes were carried out near Kobani.

U.S.-led forces conducted 16 air strikes in Syria, most of them around Kobani near the Turkish border, and seven in the oil-producing northern region of Iraq since Monday, the U.S. Central Command said.

Ten air strikes conducted by the United States and its allies near Kobani hit eight small ISIS units, damaged three fighting positions and destroyed a logistics facility, Centcom said Wednesday in a statement.

In Iraq, five air strikes near Baiji, home to an oil refinery, struck one large ISIS unit, three small ones and destroyed two buildings, two vehicles and a sniper position used by the militants, it said. The other two strikes hit near the oil city of Kirkuk in Iraq's Kurdish dominated north.
