INTERNATIONAL: Ukrainian fighters were clinging to their last redoubt in Mariupol after Russian President Vladimir Putin claimed victory in the biggest battle of the war, declaring the port city "liberated" following weeks of relentless bombardment.
FIGHTING
* Ukraine President Volodymyr Zelenskiy said Russian forces control most of Mariupol but Ukrainian troops remain in a part of it. About 120,000 civilians were blocked from leaving, he said.
* Hundreds of Ukrainian troops remain bunkered down at Mariupol's Azovstal steel factory. Putin told his troops to blockade it.
* British military intelligence said a full Russian assault on the plant would likely mean heavy Russian casualties and Putin's decision to blockade it would free up forces for elsewhere in the east.

* "There's no need to climb into these catacombs and crawl underground through these industrial facilities ... block off this industrial area so that not even a fly can get through": Putin on sealing off the steel plant.
"If you have a helmet and a bulletproof vest, but you do not have a gun in your hands, you are doomed": Ukrainian Foreign Minister Dmytro Kuleba, appealing for military aid.
