Russia's defence ministry says it is ready for a humanitarian ceasefire at the Azovstal steel plant if Kyiv's soldiers holed up there surrender.
"All servicemen of the Ukrainian armed forces, militants of the national battalions and foreign mercenaries who laid down their arms are guaranteed life, decent treatment in accordance with international law, and the provision of quality medical care," Putin says, adding: "But the Kyiv regime is not allowing for this opportunity to be used."

The success of Russia's military operation in Ukraine depends on its ability to capture the strategic port city of Mariupol, the regional governor tells AFP.
"The enemy's offensive operation in the south hinges on Mariupol. The enemy is trying to focus all its efforts on it," Donetsk governor Pavlo Kyrylenko says.
Earlier Ukrainian President Volodymyr Zelensky said Mariupol "continues to resist" despite Russian claims to have captured it after besieging it for weeks.
Kyrylenko says remaining Ukrainian forces holed up inside the sprawling Azovstal steel plant are "holding on" and have ammunition but are "exhausted after two months of fighting".
