Suicide bombers strike Syrian army HQ,4 guards killed

The brazen rebel attacks in the heart of the Syrian capital highlighted their determination to bring down Assad as the countrys civil war intensifies.

Syrias unrest began in March 2011 when protests calling for political change met a violent government crackdown. Many in the opposition have since taken up arms as the conflict morphed into a civil war that activists say has killed nearly 30,000 people. Over the past few months,the rebels have increasingly targeted security sites and symbols of regime power in a bid to turn the tide in the fighting.

Rebels from the Free Syrian Army claimed responsibility for Wednesdays bombings.

The blasts went off about 10 minutes apart,starting around 7 am,near the landmark Omayyad Square. They were heard several miles away.

Syrian state TV aired what it said was security camera footage of the blasts. In the first,a white van is driving on the road outside the military headquarters,then veers to the right and explodes. The second blast goes off inside the compound,with flames rising from behind trees.

Later,the army command building is seen engulfed in flames that sent huge columns of thick black smoke over Damascus for several hours.

The explosions shattered the windows of the Dama Rose hotel and other nearby buildings,as well as windshields of parked cars. Footage by the Syrian TV channel Ikhbariya,also state-run,showed heavy damage inside the compound,with glass shards scattered across the floor and broken ceiling tiles.

The blasts caused fear among residents of a nearby upscale district,which has largely been sheltered from the violence that plagues other parts of the city.

Witnesses said the explosions were followed by heavy gunfire that stretched on for hours at the Omayyad Square and around the military compound.
