Syrian activists say four hospitals in the decimated city of Aleppo were bombarded in government air strikes launched on July 23, threatening to cut off medical care for the some 200,000 civilians living in areas controlled by rebel factions.
Activists said on July 24 that the air raids began the previous night and into the early morning, and that an infant was among at least five people killed.
The Syrian regime and its ally, Russia, regularly target rebel-held areas in Aleppo with air strikes.
The Independent Doctor's Association, which supports clinics in the city, said a blood bank was also hit in the Al-Shaar neighborhood. A two-day-old baby in a children's hospital was killed after his oxygen supply was cut off during an air raid early on July 24, the group said.
The International Committee of the Red Cross called the reports "harrowing news," saying on its Twitter feed that "civilians and hospitals are not a target."
The World Health Organization says Syria was the most dangerous place in the world for medical workers in 2015.
