At least 34 people have been killed in explosions that struck the eastern Damascus district of Jaramana, state television said.
At least 83 people were wounded in the blasts.
Addounia television broadcast footage of firemen hosing down two blackened and charred vehicles after what it described as "terrorist explosions".
It said there had been deaths and injuries, without giving numbers.
The Syrian Observatory for Human Rights, an opposition group which has monitored the violence since Syria's uprising erupted 20 months ago, said the blasts were caused by two car bombs.
