On 24 February, the Foreign, Commonwealth and development Office issued a news release advising of a new package of sanctions, including export bans on every item Ukraine has found Russia using on the battlefield to date. The new sanctions package also includes an import ban on 140 goods, including iron and steel products processed in third countries, and extension of existing measures against Crimea and the non-government-controlled areas of Donetsk and Luhansk to the non-government-controlled areas of Kherson and Zaporizhzhia.
