New investigation into MH17 disaster blames Russian military for downing plane over Ukraine

A group of open-source investigative journalists have released a report into the 2014 downing of Malaysian Airlines flight MH17 over Ukraine that largely assigns responsibility for the missile attack to a Russian military unit and its chain of command - extending all the way to Russian President Vladimir Putin.
The report, published on the site Bellingcat, tracks the movement of Russia’s 53rd anti-aircraft missile brigade and its three battalions during the summer of 2014. Using social media posts, open-source imagery and various other reporting, Bellingcat’s team managed to trace the movement of a specific Buk surface-to-air missile system - of the type that shot down MH17 - to the border of Russia and Ukraine.

“Although it is likely that the head officials of Russia’s Ministry of [Defence] did not explicitly decide to send a Buk missile launcher to Ukraine, the decision to send military equipment (with or without crew) from the Air [Defence] Forces to Ukraine was likely made at a very high level and, therefore, the Russian Ministry of [Defence] bears the main responsibility for the downing of MH17,” the report concluded.
On July 17 2014, the Boeing 777 loaded with almost 300 passengers and crew was on a routine flight from Amsterdam to Kuala Lumpur when it was struck by a surface-to-air missile over eastern Ukraine. Everyone aboard was killed.
But heavy fighting between Ukrainian government forces and Russian-backed separatists around the crash site, lack of satellite imagery and little initial concrete evidence helped create a maelstrom of half-baked theories that took months to dispel.
