Russia has said that a US decision to supply advanced rocket systems and munitions to Ukraine was extremely negative and would increase the risk of a direct confrontation. Russian deputy foreign minister, Sergei Ryabkov, said that Moscow viewed US military aid to Ukraine “extremely negatively”. “Attempts to present the decision as containing an element of ‘self-restraint’ are useless,” Ryabkov said. “The fact that the United States, at the head of a group of states, is engaged in a purposeful pumping of weapons into the Kyiv regime is an obvious thing.”
US President Joe Biden has confirmed he will send the more advanced, longer-range rocket systems to Kyiv, a critical weapon that Ukrainian leaders have been asking for as they struggle to stall Russian progress in the Donbas region. The medium-range high mobility artillery rocket systems are part of a new $700m tranche of security assistance from the US.
Serhiy Haidai, Ukraine’s governor of Luhansk, has said that Russia now controls 70% of the city of Sievierodonetsk, which is the main crucible of Russia’s attack at the present time, and a key objective if Russian forces are to control the whole of the Donbas region. Haidai posted to Telegram claiming that “the Russians control 70% of Sievierodonetsk. Ukrainian troops retreated to more advantageous, pre-prepared positions. Another part continues fighting inside the city.”
President Zelenskiy has blasted the “madness” of bombing a chemical plant in Sievierodonetsk. “Given the presence of large-scale chemical production in Sievierodonetsk, the Russian army’s strikes there, including blind air bombing, are just crazy.” Local officials said a nitric acid tank was hit and posted images of pink smoke billowing.
Zelenskiy said Ukraine’s military forces have had some successes near Kherson and in parts of the Kharkiv region.
The UK’s ministry of defence latest assessment of the situation on the ground in Ukraine says: “Russian ground operations remain tightly focused, with the weight of fire power concentrated within a small sector of Luhansk oblast. Over 30-31 May, fighting intensified in the streets of Sievierodonetsk, with Russian forces pushing closer to the town centre. Over half of the town is likely now occupied by Russian forces, including Chechen fighters. Beyond the Donbas, Russia continues to conduct long-range missile strikes against infrastructure across Ukraine.”
