Syrian government forces retook a neighborhood from Islamic State fighters in a northeastern city on Tuesday, days after it was captured by the extremists, state TV reported.

The IS group attacked several government-held southern neighborhoods of the city of Hassakeh last week. The fighting has continued since then, leaving dozens dead, according to activists.

Until the IS push, the predominantly Kurdish city was split between government forces and Kurdish fighters.

State TV says troops and the paramilitary National Defense Forces regained control of the Eastern Ghoweiran neighborhood on Tuesday.

Turkey-based opposition figure Mustafa Osso said IS captured three predominantly Arab neighborhoods in Hassakeh last week. He says fighting is still underway.

The U.N. said the IS attack that began last Thursday has displaced at least 60,000 people.

In the eastern province of Deir el-Zour, meanwhile, IS fighters beheaded two women they accused of practicing sorcery, said the head of the Britain-based Syrian Observatory for Human Rights, a monitoring group which relies on a network of activists inside Syria.

Rami Abdurrahman said one of the women was beheaded along with her husband. He said the beheadings were carried out over the past week.

The IS group, which governs its self-styled caliphate in accordance with an extreme interpretation of Islamic law, has beheaded dozens of people for blasphemy, sorcery and espionage.
