An eyewitness to the events surrounding the downing of MH17 has given testimony to Russian investigators using a polygraph test, providing a clear and consistent account of events leading up to the tragedy.

MOSCOW, December 24 (Sputnik) – A polygraph test has verified claims by a former Ukrainian airbase employee who suggested in a newspaper interview earlier this week that flight MH17 was possibly downed by a Ukrainian air-to-air missile, a Russian Investigative Committee spokesperson said Wednesday.

The witness, whose name was not disclosed to protect his relatives still living in Ukraine, said in an interview with the Komsomolskaya Pravda newspaper earlier this week that he saw a Ukrainian Air Force Su-25 combat jet taking off from an airbase in eastern Dnipropetrovsk carrying air-to-air missiles and returning without them on the day of the MH17 crash.

"The facts and information obtained from the witness, who was able to recall them clearly and consistently, confirms to be true to the investigators and, besides, his testimony was verified in a polygraph test," spokesperson Vladimir Markin told journalists.

"The investigative committee will continue gathering and analyzing all information about the disaster. If members of an international commission investigating the crash are indeed interested in finding out the truth and decide to request information from us, we are ready to share all available data," Markin said.

On July 17, Malaysia Airlines flight MH17 , en route from Amsterdam to Kuala Lumpur, crashed in eastern Ukraine, killing all 298 people on board.

In September, the Dutch Safety Board released a preliminary report on the incident, saying that the plane was hit by numerous high-energy objects and broke up in mid-air.

The Kiev government accused the independence supporters of Ukraine's eastern regions of shooting down the aircraft, but the latter denied the allegations, saying they were not in possession of weapons capable of downing a plane flying at the altitude of some 30,000 feet.
