A total of 66,000 people have been displaced by recent fighting along two fronts in Syria's fractured north, the United Nation's humanitarian coordination agency (OCHA) said Sunday.

"This includes nearly 40,000 people from Al-Bab city and nearby Tadef town, as well as 26,000 people from communities to the east of Al-Bab" in northern Aleppo province, OCHA said.
