Ukraine’s military says it has recaptured several towns from Russian forces, including Irpin, a strategic suburb outside the capital Kyiv. Meanwhile, the mayor of Mariupol said nearly 5,000 residents — including 210 children — have died in Russia’s assault on the besieged city, which was home to nearly half a million people before Russia’s invasion.

On Monday, United Nations Secretary-General António Guterres called for an immediate ceasefire.

Secretary-General António Guterres: “A cessation of hostilities will allow essential humanitarian aid to be delivered, and enable civilians to move around safely. It will save lives, prevent suffering and protect civilians.”
