Syrian state media say a suicide bombing in central Damascus has killed and injured dozens of people.
State television showed footage of the scene and said the casualties were mostly civilians.
State TV said at least 10 people were killed but local Adounia TV put the death toll at 25.
The reports said "terrorists" were responsible for the blast, which occurred on January 6
In a similar bombing in late December in Damascus, authorities said two suicide car bombers killed at least 44 people.
Opposition activists accused the government of staging those blasts.
For some 10 months, Syria has been the scene of an uprising against President Bashar al-Assad.
The United Nations estimates that more than 5,000 people have been killed during the violence.
Authorities have blamed the turmoil on "armed gangs."
This latest blast comes as an Arab League observer mission tasked to protect civilians is in Syria.
Rights activists say the mission is a failure and are calling for UN help to end the violence.
