  • Ukraine’s president, Volodymyr Zelenskiy, has praised his people’s bravery and resolve on the 50th day of war, calling Russia’s invasion “absurd” and “suicidal” in his latest national address. “We have withstood 50 days already. Fifty days of Russian invasion, although the occupiers gave us a maximum of five,” he said.

  • The Russian flagship cruiser Moskva has sunk in the Black Sea off southern Ukraine, according to Russia’s defence ministry. Ukraine claims it was hit by Ukrainian weaponry – the Neptune cruise missile, which Ukraine builds itself. Russia maintains that a fire onboard and then “stormy sea conditions” while it was being towed to port were to blame. Russia has only three of this flagship-class of warship, which have crews of almost 500 sailors, and the loss of the Moskva is a big blow. The former CIA director David Petraeus described Russia’s admission as a “rare moment of truth”, telling the BBC: “I’m surprised that they admitted it.”

  • Moskva served a “key role as command vessel and air defence node”, the UK’s Ministry of Defence said.

  • Vladimir Putin may resort to using a tactical or low-yield nuclear weapon in light of military setbacks in the invasion of Ukraine, the CIA director, William Burns, has said. During a speech in Atlanta, Burns said: “Given the potential desperation of President Putin and the Russian leadership … none of us can take lightly the threat posed by a potential resort to tactical nuclear weapons or low-yield nuclear weapons.” The Kremlin placed Russian nuclear forces on high alert shortly after the invasion of Ukraine began on 24 February.

  • A total of 6,673 alleged war crimes committed by Russian troops in Ukraine are under investigation, Ukraine’s prosecutor’s office has said. 198 children have been confirmed to have been killed, the office added.
