Bombers strike Aleppo,48 dead

The state news agency SANA said suicide bombers detonated two explosive-laden cars in the main square,Saadallah al-Jabiri,which is lined on its eastern flank by the military club,two hotels and a telecoms office.

The explosions reduced at least one building to a flattened wreck of twisted concrete and metal,and were followed by a volley of mortar bombs into the square and attempted suicide bombings by three rebels carrying explosives,it said.

Another bomb blew up a few yards away on the edge of the Old City,where rebels have been battling Assads forces.

State television showed three dead men disguised as soldiers in army fatigues who it said were shot by security forces before they could detonate explosive-packed belts they were wearing. One appeared to have a trigger device strapped to his wrist.

Another pro-Assad station,al-Ikhbariya TV,broadcast footage of four dead men,including one dust-covered body being pulled from the rubble of a collapsed building and loaded onto the back of a pickup truck.

The facades of many buildings overlooking the square were ripped off and a deep crater was gouged in the road.

The Syrian Observatory for Human Rights said 48 people were killed,mostly from the security forces,while SANA put the death toll at 31.

Wednesdays attacks in Aleppo followed last weeks bombing of the military staff headquarters in Damascus,another strike by Assads outgunned opponents against bulwarks of his power.

In July,rebels killed four of Assads senior security officials including Assads brother-in-law,the defence minister and a general in a Damascus bombing which coincided with a rebel offensive in the capital.

Government forces have since pushed rebel fighers back to the outskirts of Damascus. But they have lost control of swathes of northern Syria as well as several border crossings with Turkey and Iraq and failed to push the fighters out of Aleppo.
