Russian Ambassador to Malaysia Lyudmila G. Vorobyeva said here Tuesday in a press conference that the accusations of Russia's involvement in the MH17 incident were groundless.

She said a Ukraine combat aircraft flying on the same route of MH17 was detected by the Russian armed forces, which proved that " what is said about Russia and Russia's role in this awful tragedy is groundless in a very big extent."

The ambassador said that Russia had been calling for a fair, transparent and full investigation by the international experts from the beginning.

Meanwhile, she said it was also not fair to squarely blame the pro-Russian separatists on shooting down of MH17. "If you ask me, I am convinced that there is no way they could have done it. They don't have the means to do it," she said.

"I am not a military expert, but that BUK missile system is very sophisticated that you need special training to operate it," she said, adding that "the rebels did not have the book or qualification to operate it, but the Ukrainian military have it."

Moreover, she also dismissed accusations that the rebels had hindered the investigation, saying that the rebels were "eager to cooperate" from the first day the incident occurred.
