First-aid workers and self-proclaimed Prime Minister of the pro-Russian separatist "Donetsk People's Republic" Alexander Borodai (back-C) gather on July 17, 2014 on the site of the crash of a malaysian airliner carrying 298 people from Amsterdam to Kuala Lumpur, near the town of Shaktarsk, in rebel-held east Ukraine.  The plane was shot down over Ukraine by a surface-to-air missile Thursday but it was unclear who fired the weapon, US officials said.
