The US has imposed sanctions on Elvira Nabiullina, the governor of Russia’s central bank, as part of a new package of measures intended to stiffen its financial punishment of Moscow in the wake of its annexation of vast chunks of territory in eastern Ukraine. The move against Nabiullina came as the Treasury department widened its sanctions against Russia to include several of the country’s top economic officials, in addition to individuals and legislators associated with the invasion of Ukraine. Western officials were swift to condemn Russian leader Vladimir Putin’s actions on Friday, launching a co-ordinated response that included fresh sanctions from the EU and the UK. US president Joe Biden said: “America and its allies are not going to be intimidated by Putin and his reckless words and threats. He’s not going to scare us and he does not intimate us.”
