(QHA) -

The leader of self-proclaimed Donetsk People's Republic, a stronghold of pro-Russian separatists, says the "black boxes" from the downed Malaysia Airlines Flight MH17 have been found and will be given to the International Civil Aviation Organization.

Aleksandr Borodai, the self-styled prime minister of the self-proclaimed "Donetsk People's Republic," said at a press conference in Donetsk that pro-Russian separatists have what appear to be the black boxes from the airliner, which crashed on July 17, killing 298 people.

Borodai said rebel forces had recovered "some items, presumably the black boxes," and said they were delivered to the eastern city of Donetsk, which is controlled by the separatists.

Separatist forces control the area -- near the town of Torez, close to the Russian border -- where the airliner and 298 people onboard crashed.

Thirty-two OSCE Special Monitoring Mission personnel have arrived in Ukraine to investigate the crash of the plane.
