The Boeing 777 came down near the city of Donetsk, stronghold of pro-Russian rebels, interior ministry official Anton Gerashchenko said on Facebook, adding it was “shot down with a Buk anti-aircraft system by terrorists” – the term the Kiev government uses for militants seeking to unite eastern Ukraine with Russia.
It's important to note that there has been no further confirmation on this, and Russian officials have denied any involvement or knowledge.
