Eighty-seven people were killed and at least 150 injured in two explosions that struck Aleppo University in Northern Syria this past Tuesday. Most of the casualties are students and civilians, many of whom had sought refuge from the violence of the civil war and were living in university dorms. The explosions occur in the midst of an ongoing, year old conflict between forces loyal to the Ba’ath Party and rebels. While it remains unclear what caused the explosion, students on campus are alleging that the government targeted the public university, in retaliation to peaceful protests on the campus last week.
