TOREZ, Ukraine (AP) — Pro-Moscow rebels piled nearly 200 bodies from the downed Malaysian jetliner into four refrigerated boxcars Sunday in eastern Ukraine, and cranes at the crash scene moved big chunks of the Boeing 777, drawing condemnation from Western leaders that the rebels were tampering with the site.

The United States, meanwhile, presented what it called “powerful” evidence that the rebels shot down the plane with a Russian surface-to-air missile and training. Although other governments have stopped short of accusing Russia of actually causing the crash, the U.S. was ahead of most in pointing blame on Moscow for the downing of Malaysia Airlines Flight 17 that killed all 298 people aboard.
