The Security Service of Ukraine released a video Sunday alleging Russian forces have been complicit in concealing evidence of their involvement in bringing down Malaysia Airlines Flight MH17.

The 2-minute video, which is posted on the official website of the security service, is the second to be released this week and involves an intercepted phone conversation from Friday between two soldiers in the pro-separatist group, the Donetsk People’s Republic.

The conversation between Commander Khodakovskyi and a man only identified as “Oleksiy” concerns the whereabouts of the black box recorder from the MH17. The onscreen translation, which the International Business Times had independently verified, shows Khodakovskyi saying the black box should be found quickly because “Moscow asks where the boxes are” and “They must be under our control” after Oleksiy explains the Organization for Security and Co-operation in Europe has arrived to inspect the crash site.

Twenty minutes later Khodakovskyi calls back and says “friends from high above” have reiterated their interest in fate of the black box. An hour later, at 1900 hours, according to the recording, Oleksiy says he has found an orange box with “satellite navigation block” written on it.

Khodakovskyi instructs him to hide it.

An earlier video released Thursday allegedly provides evidence pro-Russian rebels were responsible for shooting down the Boeing 777 aircraft as it traversed Eastern Ukraine Thursday en route from Amsterdam to Kuala Lampur, Malaysia, resulting in the deaths of the 298 passengers and crew members on board. That video has since been verified as a recording by U.S. intelligence analysts.
