Two hospitals have been hit in new air strikes in Syria, medics and witnesses say, causing a number of deaths and injuries, BBC reports.
MSF blamed pro-Syrian government forces for the raid in Maarat al-Numan; Turkey blamed Russia for the Azaz strike.
In Azaz on the Turkish border, at least 10 people reportedly died, including several in one hospital building.
The strikes come days after Russia and other world powers agreed to a limited cessation of hostilities in Syria.
However, Mego Terzian, president of MSF France, said the Maarat al-Numan strikes were carried out by forces “loyal to President Bashar al-Assad”.
Turkish Prime Minister Ahmet Davutoglu said a Russian ballistic missile had hit buildings in Azaz, with children among the dead.
Azaz and Tal Rifat are on the corridor stretching from the Turkish border to the city of Aleppo. This is the supply route, the lifeline for the anti-Assad rebels in the area, as it serves as a land bridge to Turkey.
The route faces threats from various sides. To the east, the so-called Islamic State group, to the west the Syrian Kurds and to the south the Assad forces.
It should be recalled that on Friday in Munich representatives of the United States, Russia and more than a dozen other countries agreed to a cessation of hostilities set to begin in a week and to provide rapid humanitarian access to besieged Syrian towns. However, Russia refused to stop bombing in Syria.
Russian Foreign Minister Sergei Lavrov told the news conference that Russia would not stop air attacks in Syria, saying the cessation of hostilities did not apply to Islamic State and al Nusrah, which is affiliated with al Qaeda.
Moreover, Russian soldiers participate in an offensive by Syrian government forces in the province of Latakia in northwestern Syria near the Turkish border.
