Syrian state-owned Al-Ikhbariya TV is reporting that two suicide bombers have blown themselves up in a central Damascus square, causing casualties.

The station showed footage of broken shop facades and mangled cars in the central Marjeh Square. Ambulance workers were seen carrying the wounded from the busy square.

Suicide attacks and car bombs have become common in Damascus. Tuesday 's twin explosions in the capital are the first since government troops captured a strategic town in the central province of Homs, the linchpin linking the capital Damascus with the regime strongholds on the Mediterranean coast.
