An explosion by terrorists targeted the central Maidan district of Damascus on Friday, Syrian state television said, adding that the attack targeted a police bus in central Damascus, causing several deaths.
Initial reports claim a suicide bomber detonated himself in the city's Maidan quarter near the Syrian intelligence headquarters, with Syria's official news agency SANA reoprting that 15 people were killed in the attack and another 46 wounded.
A resident of the conservative district, where protests against President Bashar Assad have been expanding, said ambulances were seen in the area. SANA said that the explosion took place near Hassan al-Hakeem Basic Education School.
The report came only two weeks after two booby-trapped cars blew up at Syrian security sites in Damascus, with 44 killed and dozens wounded.
Syria blamed Al-Qaida for the blasts, which hit two security buildings and came a day after an Arab League delegation arrived to prepare for monitors who will report on Syrian President Bashar Assad's implementation of a plan to end the bloodshed. Some Assad opponents said the attacks could have been staged by the government itself.
