REPUBLIKA.CO.ID, MOSCOW -- The Russian maker of BUK missiles on Tuesday sought to discredit findings of an official inquiry into the downing of a Malaysia Airlines jet over rebel-held eastern Ukraine last year.

International investigators have concluded after a 15-month probe that Malaysia Airlines flight MH17 was shot down by a Russian-made BUK fired from rebel-held eastern Ukraine, a Dutch paper said Tuesday just hours ahead of the official report.

State-controlled Russian firm Almaz-Antey showed videos of a BUK missile being exploded close to the nose of decommissioned Ilyushin plane.

The experiment, it said, disproved claims the missile was shot down from Snizhne, a village controlled by pro-Russian rebels.
