An office of the ruling Baath party was attacked in the Syrian capital, opposition activists said Sunday, dpa reported.
The office in the al-Mazra district of central Damascus was hit by rocket-propelled grenades Saturday, according to the Local Coordination Committees of Syria.
Columns of smoke were rising from the office as explosions were heard in its vicinity, the group said on its Facebook page.
No one claimed immediate responsibility for the attack.
Defectors from the army last week claimed they were behind a series of assaults on military posts near Damascus and in the dissident city of Hama.
