Summary of events in Russia's war on Ukraine on Easter Sunday
With thousands of Ukrainian fighters still held up in a steelworks plant in Mariupol, the Russian military "continues to launch missile and bomb strikes on the city," Ukraine's army headquarters said.
"The city still has not fallen," Ukraine's Prime Minister Denys Shmyhal told US broadcaster ABC. "There's still our military forces, our soldiers. So they will fight to the end."
Russia previously issued an ultimatum to Ukrainian forces to surrender or be "eliminated." No reports of surrender came from the city despite the ultimatum expiring the morning of Easter Sunday.
Ukrainian President Volodymyr Zelenskyy said he spoke with Kristalina Georgieva, the managing director of the International Monetary Fund (IMF), regarding Ukraine's financial stability and the post-war reconstruction of the country. Ukraine also asked G7 nations for $50 billion (€46 billion) in financial support.
The EU said it is allocating a further €50 million ($54 million) in funding to give humanitarian support to people affected by Russia's invasion of Ukraine. Additionally, EU Commission President Ursula von der Leyen told the Sunday edition of Germany's Bild newspaper that the EU is working on the next wave of sanctions against Russia which would affect the country's banking and energy sectors.
Russia's Ministry of Defense claimed its air defense system had shot down two Ukrainian MiG-29 fighter jets in the region of Kharkiv.
