Syrian government forces targeted restive areas in air raids across the country Tuesday, an opposition groups said, DPA reported.
A tank was also destroyed in the fighting, the organization said.
On the outskirts of the capital, the Sahm and Aqarba areas were also bombarded by air force jets.
The rebels have been fighting for control of Damascus for weeks.
The opposition also reported army shelling of the southern town of Basr al-Harir and restive areas in the north.
More than 45,000 people have been killed in Syria since the conflict started in March last year, according to the opposition. On Monday alone, 160 people were reported killed.
Information coming out of Syria is hard to verify as authorities have barred most foreign media from restive areas since the start of the uprising against President Bashar al-Assad.
