As Russia's invasion of Ukraine entered its second month, the U.N. says more than 3.7 million people have fled to neighboring countries and another 6.4 million have been displaced within the country.

In the fourth week of the war, 6.5 million people have been displaced within Ukraine and another 3.5 million people have fled for neighboring countries, according to the United Nations.
Ukrainian officials say Russian troops bombed an art school on Sunday where an estimated 400 people had taken shelter in the besieged city of Mariupol. And new curfew restrictions were imposed in Kyiv as Russian forces attacked a shopping center and several apartment buildings Sunday night, leaving eight dead.
Japan's unusually tough stance toward Russia's invasion has triggered retaliation from Moscow, though: On Monday, Russian officials announced a decision to discontinue talks with Japan over the disputed Kuril islands, citing Tokyo's sanctions against Russian invasion of Ukraine.
Here's a look at the situation on the ground in Ukraine this week:
