Two hospitals have been hit in new air strikes in northern Syria, medics and witnesses say, causing a number of deaths and injuries, the BBC reports.
In Azaz on the Turkish border, at least 10 people reportedly died, including several in one hospital building.
Medecins Sans Frontieres said eight staff members were missing after another attack in Maarat al-Numan.
The strikes come days after Russia and other world powers agreed to a limited cessation of hostilities in Syria.
It was unclear who carried out the latest attacks. MSF did not identify who was responsible for the Maarat al-Numan strikes.
