Here’s where things stand in the Ukraine conflict

• The 3am GMT deadline set by Moscow for Ukrainian soldiers in the besieged city of Mariupol to “surrender or die” has passed, with no reports from the Ukrainian or Russian sides if the city has fallen fully to Russian control. On Saturday, the Russian defence ministry said it had cleared urban areas of Ukrainian forces, and the remaining defenders were trapped in a steelworks.
• The Ukraine president Volodymyr Zelenskiy described the situation in Mariupol as “inhuman” and called on the West to prove more arms . “The successes of our military on the battlefield are really significant, historically significant. But they are still not enough to clean our land of the occupiers,” he said.
• Russian forces have renewed missile strikes on Kyiv and intensified shelling of Kharkiv, in an apparent strategy to hobble Ukraine’s defenses ahead of an expected full-scale Russian assault in the east. Explosions were heard in the early hours on Sunday in Kyiv. Russia had warned it would step up its missile bombardment following the sinking of its battleship Moskva.
• Russian air defence units have reportedly brought down a military transport plane carrying Western arms outside Odesa.
• The Ukraine president warned that the world “needs to prepare” for the possibility of Russia using nuclear weapons. On Saturday, the mayor of Trostianets, a city in Ukraine’s northern Sumy region, claimed that authorities have found the remains of chemical weapons including Sarin in the village of Bilka, which had been occupied by the Russians. The allegation has not been verified.
• Russia’s foreign ministry barred entry to the country for Johnson and other British government politicians and members in response to the government’s “hostile action” including sanctions. The Kremlin said it would expand restrictions against British politicians over what it calls a “wave of anti-Russian hysteria.”
