A car bomb has killed at least 16 people in a southwest suburb of Damascus, activists and state media said. Witnesses said the majority of those killed were children.
The explosion occurred in a residential area for soldiers in Qatana, which is near several army bases, according to the head of the pro-opposition Syrian Observatory of Human Rights.
Official state media are blaming the Syrian opposition for the blast.
The deadly blast comes one day after Europe, the USA and allies attending the 'Friends of Syria' meeting in Marrakesh, agreed to officially recognise the newly organised opposition leadership, giving it a stamp of credibility.
The deaths of dozens of Syrian security men in apparent double suicide car bomb attacks were caused by the explosion on the second vehicle, an opposition watchdog said.
The first car drove into a military camp in Deraa and exploded, followed by the second vehicle, the UK-based Syrian Observatory for Human Rights said. The information office, which is opposed to the Assad-led Government, said that the detonation of the second vehicle caused the casualties.
