Violent clashes continued between the Syrian Democratic Forces (SDF) backed by the US Special Forces on one hand and Daesh on the other in several areas in Al Raqqah city, said the Syrian Observatory for Human Rights (SOHR).
Simultaneously, a violent explosion was heard in the Old City. Information indicated it was caused by a booby-trapped car blown up by the terrorist group in the area. 
Clashes were accompanied by shelling by the “Euphrates Wrath” Operation Forces on areas in the city, amid the hovering of warplanes in the city skies and targeting of Daesh-controlled areas in Al Raqqah every now and then.
