Three men blew themselves up near the police headquarters in central Damascus on Wednesday, the second such attack to hit the Syrian capital this month, state media said.
The blasts killed two people and injured six others, it said, citing the Interior Ministry.
Two suicide bombers tried to storm the police command centre and clashed with guards before detonating explosive devices outside on Khalid Bin Al Walid street, the Damascus police chief said on state TV.
Police forces then chased down the third attacker, who blew himself up at the entrance of a clothes market.
“Our investigations are ongoing to find out where they came from and how,” Mohammad Kheir Ismail said from outside the headquarters.
