Suicide car bombings ripped through a Syrian government base in the southern city of Daraa, killing at least 20 soldiers in the latest in a series of explosions targeting regime forces and symbols of state security across the country.
The explosions were followed by clashes between regime forces and rebels fighting to topple president Bashar Assad, activists said.
"I heard two very loud explosions and a third smaller one followed by bursts of gunfire," said Mohammad Abu Houran, an activist in Daraa. He said the first two were likely to have been car bombs and the third a mortar shell or rocket-propelled grenade.
