Ukrainian newspaper has published details of phone conversations which it says are between Russian intelligence officers and separatist commanders, in which a man claims "we have just shot down a plane". The conversations, which have not been independently verified, appear to show rebels describing the carnage. One man described as a rebel nicknamed Major, says the plane was shot down by 'Cossacks from the Chernukhino roadblock', adding: "It is definitely a civilian plane... there was a lot of people on board." He later says: "I am only surveying the scene where the first bodies fell. There are the remains of internal brackets, seats and bodies." It is thought that rebels may have shot the plane with a surface to air missile in the belief that it was a Ukrainian military aircraft. A local man at Grabavo, where the wreckage landed, said: "I was working in the field on my tractor when I heard the sound of a plane and then a bang. "Then I saw the plane hit the ground and break in two. There was thick black smoke."
