Three suicide bombers blew themselves up near the main police headquarters building in Syria's capital Damascus on Wednesday, Assad regime television said.

Two of the suicide bombers detonated their explosives in front of the police headquarters on Khaled Bin al-Walid street in central Damascus, the interior ministry said in a statement carried by regime media.

"The terrorist suicide attackers tried to storm the police command headquarters... The guards opened fire on them, forcing them to blow themselves up before they entered the building and achieved their goals," it added.

The police cornered the third attacker behind the building, where he blew himself up on the street, regime media added.

One person was killed and six others were injured in the attack, which was the second such incident this month after Daesh terrorists targeted a police station in the Midan district of the city on October 2, leading to the death of at least 17 people.

There was no immediate claim of responsibility for Wednesday's attack.
