UNITED NATIONS, July 31, /ITAR-TASS/. Russia fears that Kiev seeks to destroy evidence of Ukraine’s role in the crash of Malaysia Airlines Boeing 777 plane, Russian permanent representative to the U.N. Vitaly Churkin said on Wednesday, July 30.

He said Ukrainian President Pyotr Poroshenko had ordered a ceasefire within a radius of 40 kilometres of the MH17 jet crash.

“However, the order was broken. Ukrainian officials set a new task - to mop up the area from militiamen and take the territory under control,” he said.

Such actions “violate U.N. Security Council Resolution 2136 and are fraught with the disastrous consequences for an impartial investigation of the tragedy”, Churkin said.

On July 28, the Russian delegation urged members of the U.N. Security Council to adopt “a statement for the press calling for a full, thorough and international investigation”.

“However, Russia’s proposed was blocked by certain U.N. Security Council members, who are against the implementation of Resolution 2166,” he said.

On July 17, a Malaysia Airlines Boeing 777 passenger airliner on flight MH17 from the Dutch city of Amsterdam to the Malaysian capital of Kuala Lumpur crashed in eastern Ukraine’s embattled Donetsk Region, killing all 298 people on board.
