Moscow; Dec. 26: A plane crash near Kazakhstan’s Aktau city, which killed 38 passengers on board, was likely caused by Russian anti-aircraft system, the Wall Street Journal has reported. Authorities in Russia and Azerbaijan, however, have offered different reasons for what may have led to the crash, citing preliminary investigations.

According to the WSJ report, an alert to airlines by UK-based independent aviation security firm, Osprey Flight Solutions, statesd that the flight “was likely shot down by a Russian military air-defence system.” The chief intelligence officer of the firm was also quoted stating the same in an interview. “Video of the wreckage and the circumstances around the airspace security environment in southwest Russia indicates the possibility the aircraft was hit by some form of antiaircraft fire,” said Matt Borie.
