A top pro-Russian separatist commander in eastern Ukraine today denied Dutch findings blaming the downing of Flight MH17 on a Russian missile fired from rebel-held territory.

"The forces of the People's Republic of Donetsk could not have fired at the plane from a BUK system because we have no such sort of weapons," general Eduard Basurin of the self-proclaimed republic told AFP.

A criminal inquiry in the Netherlands found today that the missile that shot the Malaysia Airlines Boeing 777 out of the sky was snuck out of and back into Russia.

The investigators also confirmed that the missile that slammed into the plane was fired from a field in a part of eastern Ukraine under the control of the separatists at the time.

But the Dutch-led investigation did not directly accuse Moscow of supplying the BUK missile and its transporter system-- and the Russian government has repeatedly denied any involvement.
