Chief of Staff of the Security Service of Ukraine Oleksandr Tkachuk said at today's briefing, Censor.NET reports citing UNIAN.
"Given that weapons, explosives are delivered to the territory of Ukraine from the territory of the Russian Federation, the explosive that detonated under the OSCE vehicle could have been delivered exactly from the Russian territory," he said.
"We hope for an effective cooperation with the OSCE so as to be able to investigate all the circumstances around the incident from a procedural point of view," Tkachuk added.
As reported, a United States national was killed in OSCE SUV blast April 23 near the village of Pryshyb in the militants-held territory of Ukraine's eastern Luhansk region. Two more monitors, nationals of Germany and the Czech Republic, were injured.
