The United Kingdom's Foreign Secretary Liz Truss has announced further sanctions against 63 Russian citizens and entities, including against Russian media companies "behind Putin's vicious disinformation campaign" and their employees.
Russian war correspondents embedded with Russian forces in Ukraine and several Russian media outlets are among those sanctioned.
Aside from asset freezes and travel bans, new legislation introduced means social media, internet services and app store companies "must take action to block content from two of Russia's major sources of disinformation, RT and Sputnik," according to the UK's Foreign, Commonwealth & Development Office (FCDO).
"These outlets have already been booted off the airwaves in Britain and we've barred anyone from doing business with them. Now we've moved to pull the plug on their websites, social media accounts and apps to further stop the spread of their lies," Tech and Digital Economy Minister Chris Philp said.
The latest sanctions announcement also sees the UK ban service exports to Russia, prohibiting the provision of PR, management consultancy and accounting services to Russian businesses.
"Doing business with Putin's regime is morally bankrupt and helps fund a war machine that is causing untold suffering across Ukraine," Truss said, adding that "cutting Russia's access to British services will put more pressure on the Kremlin and ultimately help ensure Putin fails in Ukraine."
UK services currently make up 10% of Russian imports in these sectors, according to the FCDO.
