Clearing Russia from presumed involvement in the downing of Malaysian Airlines Flight MH17, German intelligence officials say they have “unambiguous” evidence that the crash was caused by pro-Russian separatists in Ukraine, Der Spiegel reported Sunday.

The information was presented earlier this month to members of a parliamentary control committee by the president of Germany’s foreign intelligence service, the Bundesnachrichtendienst (BND), Gerhard Schindler.

“The BND has intelligence indicating that pro-Russian separatists captured a BUK air defense missile system at a Ukrainian military base and fired a missile on July 17 that exploded in direct proximity to the Malaysian aircraft, which had been carrying 298 people,” Der Spiegel reports.

Citing “unambiguous findings,” which includes satellite images and “diverse photo evidence,” the BND has concluded that pro-Russian separatists had used a Russian Buk missile defense system from a Ukrainian base to fire a rocket that exploded directly next to the Malaysia Airlines plane, killing all 298 people on board.

“It was pro-Russian separatists,” Der Spiegel quotes Schindler as saying.
