Moscow on Wednesday described as "biased" and "politically motivated" the Dutch-led inquiry into the downing of Flight MH17 over eastern Ukraine, which concluded the plane was shot down by a missile brought from Russian territory.

"Russia is disappointed that the situation around the investigation of the Boeing catastrophe is not changing," foreign ministry spokeswoman Maria Zakharova said in a statement, adding: "The conclusions... confirm that the investigation is biased and politically motivated."
