DAMASCUS, Sept. 4 (Xinhua) -- At least 14 civilians were killed over the past 24 hours by U.S.-led airstrikes on Syria's northern city of Raqqa, the key stronghold of the Islamic State (IS) group, according to state news agency SANA.
The airstrikes targeted the Naim roundabout in Raqqa, causing also huge property losses, said SANA.
The attack is the latest in a string of airstrikes that have caused civilian casualties in Raqqa.
Last month, a total of 78 civilians were killed by U.S. strikes on areas in Raqqa.
The United States has been heavily backing the Kurdish-led Syrian Democratic Forces (SDF) in their push to capture Raqqa from IS.
The heavy support enabled the SDF to capture over 60 percent of Raqqa city following a two-month battle.
But the falling of civilians on daily basis pushed the Syrian government to condemn the U.S.-led coalition and its "crimes" in Raqqa, urging the UN to dissolve the coalition.
