The nature of the targets hit by the blasts is contested. Syrian state television has reported an explosion near a hospital and a school in the Municipal Stadium district of the city killed 17 people and wounded at least 40 others. The Noble Aleppo brigade of the Free Syrian Army claimed responsibility for the attack, saying that the the hospital had been converted into an army barracks and that the neighbourhood had been emptied of residents. They claim 200 soldiers where killed or wounded in the attack, which involved a bomb smuggled into the building by a rebel sympathiser within the security forces. The second bomb attack appears to have struck a military police headquarters.
FSA fighters had previously overrun an army barracks in the city, which was subsequently bombed y Syrian government warplanes.
