A suicide bomber blew himself up on Monday in a central neighborhood of theSyrian capital where major security compounds are housed, according to a Syrian army source.
The army source told state television the security forces had killed all the members of "a terrorist group" in the bustling Rukn al Din district during a chase after a suicide bomber blew himself up.
The source did not say whether there were any casualties but a resident contacted by Viber said the army had sealed off the main streets of the congested part of the capital adjacent to key government installations and embassies.
Security forces detained scores of people after the explosion rocked the dense residential and commercial quarter, which is a main crossroad of the city and is home to many Syrian Kurds.
