Coalition bombing kills at least 56 civilians
At least 56 civilians were killed on Tuesday in air strikes north of the besieged Islamic State-held city of Manbij in northern Syria, and residents said they believed the attack was carried out by U.S.-led warplanes, a monitoring group said.
The Britain-based Syrian Observatory for Human Rights said the dead included 11 children, and that dozens more people were wounded.
The U.S.-backed Syria Democratic Forces (SDF), an alliance of Kurdish and Arab fighters, launched an offensive at the end of May to seize the last territory held by Islamic State (IS) insurgents on Syria's frontier with Turkey.
Supported by U.S. coalition air strikes, the SDF has surrounded and fought their way into parts of the city, but Islamic State attacks still occur in some areas of the surrounding countryside.
