A car bomb killed an undetermined number of soldiers and wounded at least 20 others at an army checkpoint near a military airport in Damascus, the Syrian Observatory for Human Rights said.
"There are at least 20 soldiers wounded, there are also some dead but we don't know how many," said the Observatory.
Yesterday's explosion, close to the Mazzeh military airport in the western suburbs of Damascus, was heard in several neighbourhoods in the capital and flames were visible from a distance, the Britain-based group said.
The last attack in the capital was on Tuesday, when when twin suicide bombers targetted a police station in the city centre killing at least 14 people and wounding more than 30 others.
A series of attacks have hit Damascus in recent months, most of them aimed at security check points, soldiers or government buildings.
