Syrian activists say government troops have killed at least 75 rebels over 24 hours in battles for control of the capital, Damascus.
The death toll reported by the Britain-based Syrian Observatory for Human Rights on Monday included 49 rebels killed in an ambush in Damascus' northeastern suburb of Adra early Sunday. The group says an elite unit loyal to President Bashar Assad ambushed the rebels as they were trying to push into the city.
Syrian state news agency SANA reported the ambush Sunday, without giving a casualty figure.
The Observatory reported that another 17 rebels died in fighting Sunday in central Damascus, while another nine were killed in its suburbs.
It was one of the deadliest days for the opposition in the 2-year-old conflict, which has killed 93,000 people.
