Malaysia Flight 17 Crash Scene

Members of the Ukrainian Emergency Ministry prepare to remove a body at the crash site of Malaysia Airlines Flight 17 in the rebel-held Donetsk region of eastern Ukraine on July 19, 2014. Pro-Moscow militants have allowed the Ukrainians workers access to the site but Ukrainian officials complained that the militants are refusing to let the remains be removed.

All 298 passengers were killed when the Boeing 777 crashed into a field near the border with Russia. Speculation is swirling over what was behind the disaster, with some experts alleging that a Russian-made SA-11 Buk missile struck the Kuala Lumpur-bound plane.
