An airstrike in northern Syria on a Medecins Sans Frontieres (MSF) hospital left seven people dead. It prompted the organisation to blame the Syrian government or Russia for the raid, calling it a deliberate attack. According to MSF, eight more people are missing from the attack.

Another strike on two more hospitals and a school in Azaz killed 22 people. According to Amnesty International, the airstrikes on hospitals tantamount to war crimes. The critics of the Syrian government also said that the latest violence is another indication that “cessation of hostilities” in the region is a far cry, the CNN reported.

Fifteen people were killed when a hospital and a school housing were struck, displacing people in Azaz, in Syria’s Aleppo province. Around 40 people were wounded in the strike.

Under international humanitarian laws, attacks on medical facilities are forbidden. The raids came days after Russia and other world powers agreed on the cessation of hostilities in the region, which was due to begin this week.

The five years of war in Syria has led to the deaths of 250,000 people and more than 11 million people have been displaced.

The BBC reported that, according to MSF, its hospital in Maarat al-Numan was struck by four back to back missiles.

Sam Taylor, the spokesman for MSF operations in Syria said that this “leads us to believe that… it wasn’t an accidental attack, that it was deliberate.”

Mego Terzian, president of MSF France, said that either the Syrian government or Russia was responsible for the raid. The MSF has warned that the Monday’s attacks have left scores of people without medical care in Idlib.

The Syrian Observatory for Human Rights, a UK-based organisation that works on the basis of a network of sources on the ground, said nine people including a child was killed in the attack. It added that the raid also left a number of people injured.
