The Ukrainian government said on Saturday that it had proof that Russia had provided the surface-to-air missile system that shot down a Malaysia Airlines passenger jet over eastern Ukraine on Thursday, killing all 298 people aboard.
At a news conference in Kiev, Vitaly Nayda, the head of counterintelligence for the Ukrainian State Security Service, displayed photographs that he said showed the three Buk-M1 missile systems on the road to the Russian border. Two of the devices, missile launchers mounted on armored vehicles, crossed the border into Russia about 2 a.m. Friday, or less than 10 hours after the jet, Flight 17, was blown apart in midair, he said. The third weapon crossed about 4 a.m.
