Six medical facilities were struck, including a pediatric unit, in late July.
In the past 24 hours, at least 72 people have been killed in Aleppo, monitoring groups say.
Around 95 percent of Aleppo's doctors have been killed or detained, or have fled the city.
According to a new report, almost all the city's physicians have fled, been killed or been detained during Syria's civil war.
NGOs say 313 medical facilities have been struck since war broke out in 2011.
