A rescue worker shows a flight data recorder to a colleague at the crash site of Malaysia Airlines Flight MH17 in Hrabove July 18, 2014 in this still image taken from video. Rescue workers have recovered a "black box" flight recorder from the wreckage of the Malaysian airliner that Kiev says militants shot down with a missile, Reuters video shows. The images show men wearing Ukrainian Emergency Ministry uniforms in the village of Hrabove, in the eastern Donetsk region. Walking away from emergency vehicles parked at a rural roadside, the men appear to conduct a co-ordinated search through wheat fields at the crash site. One man is later seen walking across the field carrying the orange-coloured flight data recorder and handing it to a colleague. Audio from another man who is not viewed can be heard saying "flight recorder", in Russian. The images were recorded on Friday. Video taken July 18, 2014.

Donetsk, Ukraine - A separatist leader said on Sunday they were keeping what they presumed were the black boxes from the downed Malaysian airliner in the eastern city of Donetsk, but they would need experts to confirm that they were the plane's flight recorders.

“Some items, presumably the black boxes, were found, and they have been delivered to Donetsk and they are under our control,” Aleksander Borodai, prime minister of the self-styled Donetsk People's Republic, told a news conference.

“There are no specialists among us who could pinpoint the look of the black boxes, but we brought to Donetsk some technical items which could be the black boxes of the airliner.”

Another rebel official, Sergei Kavtaradze, said he thought there were two of the presumed black boxes. - Reuters
