AMMAN (Reuters) - A powerful blast caused by a suicide bomber hit a heavily policed district of the Syrian capital on Thursday with at least seven killed, a police source told state television.
The source was quoted by state television as saying a suicide bomber blew himself in the Kafr Sousa neighbourhood where some of Syria's main security installations are located.
The British-based Syrian Observatory for Human Rights which tracks violence across the country said the death toll was expected to rise with several of the wounded in a critical condition.
Footage on state media showed splattered blood and wreckage of several cars with dozens of heavily armed security personnel at the site of the explosion.
Last July a car bomb also hit Kafr Sousa near an Iranian school in an attack that killed several people in the area, close to the main Umayyad Square (NYSE:SQ) that connects the city with several highways.
Insurgents fighting to topple President Bashar al Assad say the district houses many recruits from Iranian-backed militias fighting alongside the army.
