Damascus blast kills, wounds Syrian troops
At least 20 Syrian soldiers were killed or wounded in an explosion at a checkpoint near the key Mezzeh military airport in Damascus, a pro-opposition group said, dpa reported.
The blast late Sunday is believed to be a car bomb attack, the Britain-based Syrian Observatory for Human Rights activists group reported.
State television said it was a "terrorist attack."
Videos posted online by activists showed ambulances heading to the airport, a major military base for President Bashar al-Assad's elite forces and the closest facility to one his presidential Palace.
Rebels have increasingly targeted government buildings in recent months in the Syrian capital in their battle to oust al-Assad.
The conflict, which began with anti-government protests in March 2011, has killed more than 93,000 people, according to UN estimates.
