When US President Barack Obama spoke about the downing of flight MH17 in Washington on Friday, he struck a note of caution on the conclusions that could then be drawn over its fate.
But in the past 48 hours, open-source intelligence and information gathered by national intelligence agencies has built up a compelling body of evidence that to leave little doubt over what – and who – shot down the Malaysian airlines jet and its 298 passengers over eastern Ukraine.
A trove of evidence suggests that pro-Russian separatists and Russian military personnel shot down MH17, by mistake, with a Buk-M1 surface-to-air missile launcher from near the towns of Snizhne and Torez – although this cannot be independently verified.
