The Russian Ministry of Foreign Affairs announced Thursday that it will impose travel restrictions on British diplomats, prohibiting them to travel outside of a 75-mile radius of the British Embassy in Moscow or the British Consulate in Yekaterinburg without advanced notice. According to the Russian MFA, the move comes in response to ‘hostile actions’ from the UK.

In a statement, the Russian MFA said, “We reiterated to the British side that any of its efforts aimed at continuing the destructive line in international and bilateral affairs, attempts to demonize our country, complicate the work of Russian foreign agencies will inevitably receive a decisive response.”

The restrictions will not apply to British Ambassador Deborah Bronnert, but the restrictions will apply to interim charge d’affaires and Deputy British Ambassador Tom Dodd.

This comes in response to the UK government’s continued support for Ukraine in combatting Russia’s ongoing invasion of the country. Since the outset of Russia’s so-called “special military operation” in Ukraine, Britain has led the way in its support for Ukraine through the provision of defensive weaponry.

Under Article 26 of the Vienna Convention on Diplomatic Relations, countries have an obligation to ensure free movement of diplomats within their territory:

Subject to its laws and regulations concerning zones entry into which is prohibited or regulated for reasons of national security, the receiving State shall ensure to all members of the mission freedom of movement and travel in its territory.

UK Foreign Secretary James Cleverly also announced 14 new sanctions on July 18, including 11 against those involved in the forced deportation of Ukrainian children, according to a statement released by UK Foreign Ministry. Those sanctioned include Russian officials Ksenia Mishonova, Commissioner for Children’s Rights in the Moscow Region, and Sergey Kravtsov, Russia’s Minister of Education.
