Another two strong explosions in Syrian capital

Two explosions have hit Umawiyeen square near the chief of staff headquarters in the Syrian capital, Damascus. Iranian Press TV informs about this.
The explosions were followed by gunfire in several districts of the Syrian capital.
The Free Syrian Army (FSA) has reportedly claimed responsibility for the two blasts.
Earlier on Tuesday, a bomb planted by anti-government insurgents at a school building in Damascus left at least seven people injured.
Clashes in Syria strated since March, 2011. The rebels claim President Bashar al-Assad must resign. Assad claims that the rebels are directed by the Western forces.
