BEIRUT — An activist group says shelling by Syrian regime forces has killed at least 11 people, including women and children, in a southern city.

The British-based Syrian Observatory for Human Rights says at least three children and four women were among those killed when government forces struck a building in in the southern city of Daraa.

The Observatory's chief, Rami Abdul-Rahman, says the attack happened late on Saturday.

There have been frequent clashes lately in the city and province of Daraa between President Bashar Assad's troops and the mostly Sunni rebels fighting to overthrow his regime.
