"I'm seeing reports Russia-subordinated personnel fired a weapon to intimidate unarmed OSCE_SMM monitors in eastern Ukraine. OSCE_SMM risk their lives to protect civilians. Russia should stop this deplorable behavior before more SMM personnel are killed & get out of Ukraine," Nauert wrote on Twitter.

As UNIAN reported earlier, the OSCE Special Monitoring Mission to Ukraine in its daily spot report on Friday said its patrol was harassed by warning shots on the part of Donbas militants.
