Activists say intense Syrian government shelling has killed eight women and girls in the southern province of Daraa.

The Britain-based Syrian Observatory for Human Rights said Friday the late night attack on Karak, in eastern Daraa, killed four women and four girls. The Observatory relies on a wide network of activists on the ground in Syria for its information.

Syria state news agency said regime forces were chasing "terrorist cells" in Daraa province, including along the border with Jordan. It did not mention Karak.

SANA said 18 opposition fighters including Jordanians, a Saudi and a Chechen, were killed. It did not refer to civilian casualties.

The United Nations says more than 6,000 children are among more than 93,000 people killed in Syria's civil war.
