More than 60 health facilities in Syria supported by the Doctors Without Borders (MSF) charity were hit in attacks last year, with a dozen completely destroyed, the group said Thursday, according to AFP.

In a new report, MSF warned Syria's health infrastructure "has been decimated", with frequent aerial assaults and shelling of hospitals and clinics, in violation of international law.

The report comes days after an MSF-supported facility in the northwestern province of Idlib was hit in an air strike that killed 25 people.
