It said that a volunteer from the Azerbaijan Red Crescent Society had been killed and two others injured in the shelling.“These latest exchanges signal that the Nagorno-Karabakh conflict risks spiralling out of control,” Martin Schuepp, the ICRC’s Eurasia regional director, said in a statement. “Civilian lives are being lost at an alarming rate.”Nagorno-Karabakh is internationally recognised as part of Azerbaijan but is populated and controlled by ethnic Armenians.
