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 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.
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.
