Human Rights Watch (HRW) confirmed that the Syrian government's fighter planes had fired rockets on the main emergency hospital in Aleppo on Tuesday. The hospital had also been attacked two days prior by government aircraft, as well as a nearby school. Four civilians were killed and three wounded.
HRW visited the hospital after the attack, where hospital staff told them that no opposition fighters were at the hospital, only armed guards providing security.

HRW's Emergencies Researcher, Ole Solvang, said,
“Fighter jet attacks on a hospital twice in three days indicate that this was no accident. By firing rockets at a clearly marked hospital, the government shows blatant disregard for civilian lives.”
“Hospitals, doctors, and ambulances should never be attacked. In Aleppo, the Syrian government has flouted this principle of international law.”
