Dutch investigators revealed the findings of their long-running investigation on Thursday. They said the Russian-made BUK missile that brought down the Malaysia Airlines jet over Ukraine in July 2014  was from a military unit based in the city of Kursk.  

Speaking in Saint Petersburg, Russian president said the findings could not be trusted because his country had not been involved in the investigation.

On the same day, Russia's defence ministry claims the missile "more than likely belonged to the Ukrainian armed forces". It said on Friday that fragments indicated the Soviet-made missile was made in 1986, but that the Russian military decommissioned missiles of that type in 2011.
