Russian propagandists from the NTV TV channel have released a deepfake featuring Oleksii Danilov, Secretary of the National Security and Defence Council of Ukraine, attempting to convince audiences that “Ukraine was involved in the 22 March terrorist attack.”
All you need to know in order to know that Ukraine was not responsible is Ukraine outright stating that they are not responsible.
Because if they were responsible, they’d be telling everyone in no uncertain terms that Moscow was not safe from Ukrainian reprisals and this was just a warning.
One thing Ukraine has shown so far, is they aren’t stupid. The last thing they would do anyway is attack civilians.
