Two car bombs exploded in southern Syria and a rocket slammed into a building in the north, killing at least 12 people in a spike in civil war violence Friday, January 18 that Syrian state media blamed on rebel fighters trying to topple President Bashar Assad and rebels attributed to government forces, the Associated Press reported. The rocket attack in the northern city of Aleppo and the suicide car bombings in Daraa, south of Damascus, occurred during a particularly bloody week nearly two years after an uprising began against Assad’s regime. On Thursday, opposition activists said pro-government militia swept through a town in central Syria, torching houses and killing more than 100 people. And on Tuesday, 87 people were killed in twin blasts at Aleppo University. The regime said rebels hit the university with rockets. Rebels said the deaths resulted from regime airstrikes.
