A UN board of inquiry formed last summer to investigate attacks on civilian establishments in Syria, including hospitals, has refrained from directly holding Russia responsible, according to a summary of its report.
The coordinates of the sites had been communicated to the belligerents by the United Nations precisely to protect them from air strikes.
The summary obtained Monday by AFP noted that UN investigators were unable to visit the sites of the attacks because the Syrian government "did not respond to repeated requests for the issuance of visas to the members of the board."
