Syria: Dozens killed in huge Damascus explosions Updated at 2:15 p.m. (CBS/AP) DAMASCUS, Syria - Two suicide car bombs ripped through the Syrian capital Thursday, killing at least 55 people and tearing the facade off a military intelligence building in the deadliest explosions since the country's uprising began 14 months ago, the Interior Ministry said. Residents told an Associated Press reporter that the blasts happened in quick succession during morning rush hour, with an initial small explosion followed by a larger bomb that appeared aimed at onlookers and rescue crews arriving at the scene. Paramedics wearing rubber gloves collected human remains from the pavement as heavily damaged cars and pickup trucks smoldered. In addition to the 55 dead, the ministry also said there were 15 bags of human remains, meaning the death toll was likely to rise. More than 370 people also were wounded in the attack, according to the ministry, which is in charge of the country's internal security. It said the explosives weighed more than 1,000 kilograms (2,200 pounds). Victoria Nuland, a U.S. State Department spokeswoman, said the Obama administration condemned the attacks. We are concerned about the fact that this is a further indication that, far from having a ceasefire, the violence continues. It very much worries us with regard to whether the Annan plan can be implemented," Nuland said. Despite the unclear origin of the attackers, Nuland said much of the blame for the current situation rests with the Assad regime. "It is the Assad regime that created this climate of violence that is causing not only folks to take up arms in defense but is also providing an environment, potentially, for mischief to be made by others who don't favor peace in Syria," Nuland said.
