Oleksii Reznikov says Russia is trying to create a sense of anxiety as a precursor to negotiations that would, presumably, allow it to keep land it has seized. Europe correspondent @adamparsons Ukraine’s defence minister says he thinks Russia is trying to "blackmail" the world into negotiations by raising the spectre of a dirty bomb. Speaking to reporters in Kyiv, Oleksii Reznikov claimed the Russian government was trying to distract from the failure of his country's military mobilisation, and also to stop Western nations from suppling armaments and equipment to Ukraine. Earlier this week, Sergei Shoigu, the Russian defence minister, claimed Ukraine was preparing to use a dirty bomb (a combination of explosive and radioactive material) on its own territory as a way of discrediting Russia. He presented no evidence and his claim was immediately denied by Ukraine, Britain, America and NATO, among others. Ukraine latest news: Putin 'won't use nukes' - as US issues warning and Russia worrie
