Local television reports that 25 people have been killed and 46 wounded by a bomb blast in the Syrian capital Damascus.
State television said a suicide bomber blew himself up at a traffic light in the central district of Maidan, where protests have intensified recently against the regime of President Bashar al-Assad.
Footage broadcast by Syrian television appears to suggest a police bus was hit. However most of the victims are thought to be civilians.
The television showed body parts, bloodstains and broken glass from the blast in the Maidan district, along with people shouting that this was the work of terrorists.
Several riot police shields could be seen in the wrecked bus, which was among a number of vehicles with smashed windows.
