In Syria, the U.S.-backed Syrian Democratic Forces say they’ve begun the battle to retake the city of Raqqa from ISIS. Raqqa is considered the de facto capital of ISIS. The U.S.-led coalition has been waging an escalating bombing campaign in and around Raqqa for months in advance of the battle to retake the city. The journalistic monitoring group Airwars says the U.S.-led coalition reportedly bombed five homes near a swimming pool Saturday, killing up to 20 civilians. Airwars also says at least 21 civilians were reportedly killed Sunday by either coalition airstrikes or artillery shelling launched by the U.S.-backed Syrian Democratic Forces.
