The Embraer 190 with 67 passengers and crew was flying from the Azerbaijani capital of Baku to Grozny in Chechnya, Russia, when it crashed in Kazakhstan on Wednesday, killing 38 people.
Investigators said they found that the Russian president likely approved the supply of heavy anti-aircraft weapons to Ukrainian separatists who shot down flight MH17 in 2014 with a Russian missile.
