Russia isn't giving up on this. They're literally using AI deepfake evidence on their national television continuing to push the Ukraine narrative:
One of Russia's major channels, NTV, has broadcast a fake video using AI-generated audio of a top Ukrainian security official in an attempt to blame Ukraine for last night's attack.
In the video, which has also been widely shared online, Ukraine's top security official Oleksiy Danilov appears to say: "It is fun in Moscow today. I think it's a lot of fun. I would like to believe that we will arrange such fun for them more often."
However, BBC Verify has established that the video is a composite of two interviews published in the last week. The voice of Danilov was likely generated using AI technology, according to an expert.
The two interviews used to create the fake video can be accessed on YouTube, one - dated 19 March - features Danilov and the other - dated 16 March - Ukraine's military intelligence chief Kyrylo Budanov.
The presenters interviewing Budanov can be seen in the fake NTV video, wearing the exact same clothes with identical backgrounds behind them.
The quote by Danilov which appears in the NTV video cannot be heard in the original interview from 16 March, making it likely that the audio is AI-generated.
Sam Gregory, an expert on AI-generated content, has told BBC Verify that the video aired by NTV was likely a "deepfake" and Danilov's voice in it appeared to be a "voice clone deepfake".
