ROZSYPNE, Ukraine (AP) -- Emergency workers, police officers and even off-duty coal miners spread out Friday across the sunflower fields and villages of eastern Ukraine, searching the wreckage of a jetliner shot down as it flew miles above the country's battlefield.

The attack Thursday afternoon killed 298 people from nearly a dozen nations - including vacationers, students and a large contingent of scientists heading to an AIDS conference in Australia.

U.S. intelligence authorities said a surface-to-air missile brought down Malaysia Airlines Flight 17 as it flew from Amsterdam to Kuala Lumpur, but could not say who fired it. The Ukraine government in Kiev, the separatist pro-Russia rebels they are fighting and the Russia government that Ukraine accuses of supporting the rebels all deny shooting the passenger plane down. Moscow also denies backing the rebels.

Russian President Vladimir Putin called for a cease-fire Friday in eastern Ukraine and urged the two sides to hold peace talks as soon as possible. A day earlier, Putin had blamed Ukraine for the crash, saying the government in Kiev was responsible for the unrest in its Russian-speaking eastern regions. But he did not accuse Ukraine of shooting the plane down and did not address the key question of whether Russia gave the rebels such a powerful missile.

The Ukrainian Interior Ministry released a video purporting to show a truck carrying the Buk missile launcher it said was used to fire on the plane with one of its four missiles apparently missing. The ministry said the footage was filmed by a police surveillance squad at dawn Friday as the truck was heading to the city of Krasnodon toward the Russian border.

There was no way to independently verify the video.
