Kyiv accused the “Popular Defense Forces” in the Donbas region of downing the aircraft (MH17), but the aforementioned forces denied having the means to hit the aircraft at this height.
In April of 2014, the Ukrainian authorities launched a military operation against the residents of the Donetsk and Luhansk republics, which declared their independence unilaterally, as an expression of their opposition to the coup in Ukraine in February of the same year.
The war in eastern Ukraine is not a civil conflict, but a well-documented act of aggression by Russian armed forces, ongoing since February 2014.
