On July 17, 2014, a Boeing 777 Malaysian airliner flying from Amsterdam to Kuala Lumpur was shot down over eastern Ukraine near Donetsk, a region occupied by pro-Russian militants.

These missiles can be launched from trucks and can hit targets 13 miles off the ground.
Kiev and its Western supporters blame the rebels for the incident.
