World leaders demanded an international investigation into the shooting down of a Malaysian airliner with 298 people on board over eastern Ukraine in a tragedy that could mark a pivotal moment in the worst crisis between Russia and the West since the Cold War.
One U.S. official said Washington strongly suspected the Malaysian Airlines Boeing 777 was downed by a sophisticated surface-to-air missile fired by Ukrainian separatists backed by Moscow.
There were no survivors from Thursday's crash, which left wreckage and bodies scattered across miles of rebel-held territory near Ukraine's border with Russia.
The scale of the disaster could prove a turning point for international pressure to resolve the crisis in Ukraine, which has killed hundreds since protests toppled the Moscow-backed president in Kiev in February and Russia annexed the Crimea a month later.
