One of the members of security watchdog of OSCE monitoring mission in eastern Ukraine was killed, another two were injured after their car struck a mine near Luhansk.
A representative of the Austrian Foreign Ministry said that a U.S. citizen was killed, and a woman from Germany was injured on Sunday morning. Austria is currently heading the Organization for Security and Cooperation in Europe (OSCE).
The German Foreign Ministry reported two wounded, but provided no details.
The OSCE confirmed on Twitter that a “serious incident” happened with a patrol of six employees on two armored vehicles, but did not provide other details.
Three years after Russia’s annexation of the Crimea, tensions between Kiev and the pro-Russian separatists in eastern Ukraine remain high, and the ceasefire agreement of 2015 is regularly violated.
The Ukrainian military reported that the incident occurred at 10:17 am local time on Sunday near a small village Prishib, which is controlled by the separatists.
“This is a terrible tragedy,” German Foreign Minister Sigmar Gabriel said.
Ukrainian President Petro Poroshenko and Austrian Foreign Minister Sebastian Kurtz on Twitter have called for an investigation of the incident.
