At least 55 people were killed and some 372 people injured by two powerful car bomb blasts in Damascus . Opposition groups denied responsibility while Haitham Maleh , a leading opposition figure , blamed the government . Media attention focused on the Al-Nusra Front , a little known jihadi-type group that had previously claimed responsibility for bombings in Damascus and Aleppo . Earlier in the week Maj. Gen. Robert Mood , head of the United Nations Truce Supervision Organization ( UNTSO ) , had expressed worries that Syria was rushing into an uncontrollable spiral of sectarian violence and following the latest bombings urged the perpetrators to refrain from violence and let the peace process move forward
