The United Kingdom on 18 July imposed sanctions on 18 officers from Russia’s Main Intelligence Directorate (GRU) and three of its units, accusing them of a years-long campaign of malicious cyber activity and hybrid warfare against the U.K. and Ukraine. The measures, announced by Foreign Secretary David Lammy, include asset freezes and travel bans under London’s Cyber Sanctions Regime and Russia Sanctions Regime, which together added 19 and four new designations respectively. The government cited GRU Unit 26165 for online reconnaissance that aided missile strikes in Ukraine and for hacking linked to the 2018 Novichok poisoning in Salisbury. The latest action follows a 7 July decision to blacklist Russia’s Scientific Research Institute of Applied Chemistry and two senior commanders—Lieutenant General Alexei Rtishchev and his deputy, Andrei Marchenko—for supplying handheld chemical grenades that U.K. officials say Russian forces used against Ukrainian troops. British authorities said the devices had deployed toxic agents such as chloropicrin in drone attacks, in violation of international prohibitions on chemical weapons. London’s twin moves broaden Western pressure on the Kremlin as the war enters its fourth year. Lammy said the sanctions were coordinated with the FBI, NATO and European partners and signalled that the U.K. “will not tolerate” attempts to destabilise Europe. Individuals and entities on the list are barred from travelling to Britain or accessing assets held in the country; U.K. persons are also prohibited from dealing with them.
