DAMASCUS, March 11 (Xinhua) -- Two explosive devices went off in a big cemetery in the capital Damascus on Saturday, leaving unknown number of people killed or wounded, state TV reported.

The two bombs exploded in the visitor's hall in the Bab al-Saghir ancient cemetery in Damascus' neighborhood of Bab al-Saghir, the TV said.

It added that there are reports of killed and wounded people in the blasts, which it branded as an act of terrorism.

The large cemetery contains graves of Sunni and Shiite people, as well as Shiite shrines.

The neighborhood of Bab al-Saghir, which the cemetery took its name from, is also a home to a blend of Shiite and Sunni Damascenes.

It's located near the Bab al-Saghir gate, one of the seven gates of old Damascus city.

The details about the explosion are still yet to come. It's not immediately known whether it was a symbolic message of sectarian hatred, or targeting certain visitors at that specific time.
