The UK has targeted the so-called "Butcher of Mariupol" in a fresh wave of sanctions, as Foreign Secretary Liz Truss condemns Putin's war as "based on a torrent of lies".

       Russian Colonel-General Mikhail Mizintsev, who gained the moniker for his role leading the brutal siege and bombardment of the city, was one of 14 additions to the sanctions list.

       Kremlin propagandists have also been targeted, including RT's managing director Alexey Nikolov, Sergey Brilev, a prominent Russian presenter on the state-owned TV channel Rossiya, and Sputnik's editor-in-chief Anton Anisimov.

       Aleksandr Zharov, the CEO of Gazprom-Media, was also added to the list.

       The measures will prevent companies and individuals operating in the UK from doing business with "Russian state propaganda vehicles", the UK government said.

       Foreign Secretary Liz Truss said she was targeting "shameless propagandists" who support Putin's "fake news and narratives".

       "Putin’s war on Ukraine is based on a torrent of lies," said Ms Truss.

       "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.

       "We will keep on going with more sanctions to ramp up the pressure on Russia and ensure Putin loses in Ukraine. Nothing and no one is off the table."

       Culture Secretary Nadine Dorries added: "Putin's propaganda machine has been working overdrive to spread misinformation and distract from his barbaric actions in Ukraine. These sanctions will target those who are complicit in covering up the Russian state's actions."

       Britain is working with its Western allies to try to cripple Russia's economy as punishment for its invasion of Ukraine, and has already sanctioned more than 1,000 individuals and businesses.

       Oligarchs and banks are among the targets.

       The fresh wave of sanctions comes after the UK put in place new legal powers to prohibit maintenance on aircraft or ships belonging to specific sanctioned Russian oligarchs or their businesses.

       Who is the 'Butcher of Mariupol' Mikhail Mizintsev?

       Mizintsev is the Chief of the National Defence Command and Control Centre, where all Russian military operations are planned and controlled worldwide.

       He is known for using reprehensible tactics, including shelling civilian centres in both Aleppo in 2015-16 and now in Mariupol - where atrocities are being perpetuated against Ukrainian people.
