Ukraine ambassador to Malaysia Olexander Nechytaylo told Malaysian press that MH17 was a deliberate attack on a civilian aircraft.
He adds that in Ukraine, they had defined the incident as a terrorist attack because it was a deliberate attack on a civilian aircraft.
This is a remarkable statement. The Joint Investigation Team so far did not make public a motive. The shot down could be a mistake as well. A motive for a deliberate shot down could be the Russian supported separatists had difficulties because Ukraine had the advantage of military aircraft. As the airspace was open for civilian aircraft, this could prevent the usage of surface to air missile which could destroy military aircraft flying at high altitudes. A deliberate shot down could be a way to force Ukraine to close its airspace.
