In the fourth week of Russia's invasion of Ukraine,
3.7 million people have fled the country and another 6.3 million people have been internally displaced, 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.
7,000 people have managed to flee Mariupol using evacuation and aid routes, although Russian forces surround the routes and have forced some to turn back.
March 25: Flames and smoke rise from a fire following an artillery fire on the 30th day of the invasion of Ukraine by Russian forces in the northeastern city of Kharkiv Russian strikes targeting a medical facility in Kharkiv on March 25, killed at least four civilians and wounded several others, Ukrainian officials said.
Ukrainian President Volodymyr Zelenskyy
addressed Israeli lawmakers Sunday, urging them to do more to aid his people. On Wednesday, he called on French companies to leave Russia in an address to the French Parliament and thanked Japan's Parliament for its support in sanctioning Russia.
In his address to French lawmakers, Zelenskyy compared the plight of Mariupol to Verdun, the French city destroyed in World War I by trench warfare. He made several appeals to liberty, fraternity and equality, too, saying he knew the French people understand his country's fight.
Japan's unusually tough stance toward Russia's invasion, meanwhile, triggered retaliation from Moscow this week: On Tuesday, Russian officials announced a decision to discontinue talks with Japan over the disputed Kuril islands, citing Tokyo's sanctions against Russian invasion of Ukraine.
March 24: A Ukrainien serviceman stands guard near a burning warehouse hit by a Russian shell in the suburbs of the capital Kyiv.
Ukrainian President Volodymyr Zelenskyy spoke to NATO leaders via video from Ukraine, repeating requests for continued and increased security assistance from the West.
The U.S., meanwhile, made public
plans to welcome up to 100,000 Ukrainians and other displaced people fleeing the conflict. Officials also disclosed that President Biden plans to announce $1 billion in new funding for humanitarian aid for Ukrainians and refugees in neighboring countries.
