Ukraine doesn't think too much of Ukrainians who have turned against their own country and support Russia in these so-called breakaway republics. Usually, they're dealt with harshly and often assassinated. In this instance though Ukraine's security forces told them they know exactly who they are and what they were talking about with the Russians by hacking into a Zoom call (Trueconf, the Russian equivalent) and letting them know their time is just about up. So very considerate of them. They then play the Ukrainian national anthem for these swine.

Ukraine's security services have hacked into a video call between Moscow and their Ukrainian supporters to tell them they have all been charged with treason - before blasting them with a rendition of the Ukrainian national anthem.

A video posted online appears to show a Ukrainian official interrupting a call attended by various representatives for the self-proclaimed Donetsk People's Republic, an area of the Donetsk region currently led by supporters Russian rule.

Several seconds later, the person filming the meeting interrupts the conference call and announces themselves as a member of Ukraine's Security Services.

The man tells those on the call: 'The Security Service of Ukraine has identified and traced all of you.

'You will all be on the international search list from tomorrow.

'You will all be held accountable under Article 111 of the Criminal Code, State treason.'

Once the man has finished speaking, the national anthem of Ukraine begins playing loudly.

Although not officially verified by government figures, those on the video certainly seemed convinced it was real as they rushed to turn off their cameras and leave the conference call.
