ISIL fighters went on a rampage killing thousands of civilians and used Raqqa city to plan attacks overseas.
Now, three years later, the US-backed Syrian Democratic Forces have launched, according to them, the final assault to take back Raqqa from ISIL. It is not clear how many ISIL fighters are still inside the city.
But an SDF spokesman says some ISIL fighters appear to be withdrawing from the province’s capital, using civilians as human shields. Others have been allowed to leave after a deal was brokered by tribal leaders on Saturday.
