A wave of suspected Russian air strikes on hospitals in northern Syria has killed as many 60 people, in one of the deadliest attacks since a nationwide ceasefire came into force.

The National and Ibn Sina hospitals in the city of Idlib were hit before midnight on Monday, leaving more than 100 injured.

Footage showed the bodies of children and babies covered in dust being pulled from the debris of a smouldering building.

One boy was seen being rescued by White Helmet emergency workers after three hours trapped.

Sharef Samadi, an opposition activist inside Idlib, told the Telegraph most of the victims had been women and children.
