Two bombs have struck the Syrian capital Damascus, according to state media and opposition activists.
A motorcycle bomb in the Rukn al-Din area killed at least five members of the security forces, state TV said.
Hours later, a car bomb struck the district of Mazzeh, near the Ministry of Information. It is not clear whether there were any casualties.
The blasts came as opposition activists said 55 people had been killed in fighting across the country on Friday.
