Russian has denied supplying BUK missiles to Ukrainian separatists accused of murdering almost 300 people flight MH17. 

The Russian Defence Ministry says the Ukrainian government has questions to answer about the shooting down the passenger jet.

It claims to have radar images of a Ukrainian military jet flying within a few kilometres of the Malaysia Airlines plane.

Meanwhile, Dutch investigators say they're satisfied with how the bodies of the victims of the MH-17 crash are being stored.

A team of three forensic scientists were today granted access to the bodies, currently being kept in refrigerated train cars in Torez - which lies rebel-controlled eastern Ukraine.

It follows international concerns about a poor management of the crash site by rebel forces - and poor procedures in the recovery of the bodies.

Dutch Investigator Pieter Van Vliet says the remains are being stored in good conditions.
