@dailymail: Russia has allegedly used its most powerful non-nuclear bomb after a terrifying video showed a huge mushroom cloud explosion in Ukraine. Footage of the blast shows a massive explosion and ball of fire erupting into the air - followed by a towering thick column of smoke rising high over the already heavily damaged village of Vovchansk in Ukraine's besieged Kharkiv region. Pool number 3 Telegram channel, with 343,000 followers, has claimed the bomb was a FAB-9000. They said: 'The Ukrainian Armed Forces have never been hit like this….the video shows the Russian army using an FAB-9000 vacuum bomb with an explosive mass of over 7 tons. There has been no official confirmation or denial from Moscow as to whether the FAB-9000 - the high-explosive aerial bomb - had been used. #ukraine #kharkiv #russia
