Russia's bloody 'Butcher of Mariupol' and a host of Kremlin television executives have been added to Britain's sanctions list.

Colonel-General Mikhail Mizintsev, who ordered a strike on a theatre that killed 300 civilians, is among 14 people and organisations hit in the latest wave of punitive economic measures unveiled by Foreign Secretary Liz Truss.

The latest names added to the sanctions list include propagandist Sergey Brilev and Kremlin-funded TV-Novosti, which owns the RT news channel.

Aleksandr Zharov, chief executive of Gazprom-Media, Alexey Nikolov the managing director of RT, and Anton Anisimov, the head of Sputnik International Broadcasting were also sanctioned.

Foreign Secretary Liz Truss said: 'Putin's war on Ukraine is based on a torrent of lies. Britain has helped lead the world in exposing Kremlin disinformation, and this latest batch of sanctions hits the shameless propagandists who push out Putin's fake news and narratives.

Olexander Scherba, Ukraine's ex-Austrian ambassador, this week branded Mizintsev the 'Butcher of Mariupol' while Oleksandra Matviichuk, head of Ukraine's Centre for Civil Liberties, called on him to face war charges.

A Foreign Office source said: 'Liz wants to keep on hitting Putin with sanctions to debilitate the Russian war economy and put Ukraine in the strongest possible negotiating position. There'll be plenty more sanctions to come.'
