A bomb blast has hit a bus carrying pilgrims in the Syrian city of Damascus, killing at least seven people and injuring several more.
At least seven people were killed when a blast ripped through a bus carrying Shiite pilgrims in a central district of the Syrian capital on Sunday, a monitoring group said.
The Syrian Observatory for Human Rights said it was not immediately clear what had caused the blast near the Souq al-Hamadiyeh neighbourhood of Damascus.
The explosion was also reported by Syrian state media, with the official SANA news agency saying at least four people had been killed and 19 wounded.
Observatory director Rami Abdel Rahman said the bus had a Lebanese licence plate and was carrying Shiite Muslim pilgrims visiting religious sites in the city.
Lebanese media reported that Lebanese nationals were among the dead and wounded, but there was no immediate official confirmation.
