At least 15 people are reported to have been killed and dozens wounded in a series of air strikes on rebel-held areas in the Syrian city of Aleppo.
Three medical facilities were hit in the space of three hours, the UN says.
One of the hospitals targeted is one of the few that still provide paediatric services. Medics have had to take babies out of incubators, the UN says.
Another strike hit near the Bayan hospital in the eastern Shaar district, activists and a monitoring group said.
Video footage, purportedly of the aftermath, showed bodies being pulled from burning and destroyed buildings.
