The Syrian Observatory for Human Rights announced that fighter jets carried out raids on dawn on Sunday on the city of Raqqa, the stronghold of the ISIS terrorist group.
The strikes coincided with strikes on the al-Jisr al-Jadeed area that connects the city to the southern bank of the Euphrates River.
Clashes between the Syrian Democratic Forces (SDF), which are backed by special US forces, and ISIS continued in the city of Tabqa, which is held by the extremists.
The SDF succeeded in achieving advances in the city and it now controls over 60 percent of the Old City. The British-based Observatory said that the forces now hold 40 percent of the city, including more than half of the Old City.
