At least 11 people were killed and 40 wounded when a car bomb exploded at a petrol station in the Syrian capital Damascus, opposition activists said.
The semi-official al-Ikhbariya television showed footage of 10 burnt bodies and Red Crescent workers searching for victims at the site.
The opposition Revolution leadership Council in Damascus said the explosion was caused by "a booby-trapped car". There was no immediate indication of who may have been responsible.
An activist who lives in the area said he saw ambulances loading burnt bodies and wounded people with severe burns before he was ordered away by security forces surrounding the station. Tow trucks removed destroyed vehicles, he added.
"The station is usually packed even when it has no fuel. There are lots of people who sleep there overnight, waiting for early morning fuel consignments," said the activist, who did not want to be named.
He said brawls have increased lately at the petrol station between militia loyal to President Bashar al-Assad and ordinary citizens waiting for fuel, but it was not known who carried out the attack.
