This weekend, in the shadows of a devastating war, Ukrainians attempted to celebrate one of their most important holidays of the year, Orthodox Easter.

Here's the latest on Russia's invasion into Ukraine if you're just joining us:

• US visit: US Secretary of State Antony Blinken and Defense Secretary Lloyd Austin met Ukrainian President Volodymyr Zelensky in Kyiv on Sunday, making them the highest-level US officials to have traveled to the country since the Russian invasion began. Blinken said during the meeting that US diplomats would return to Ukraine this week.
• Mariupol under attack: Ukrainian presidential adviser Mykhailo Podolyak said Russian forces were "continuously attacking" the encircled Azovstal steel plant in the besieged city of Mariupol on Orthodox Easter Sunday. Russian President Vladimir Putin claimed earlier this week that Russia forces had achieved the "liberation" of Mariupol, but ordered his forces to stop short of taking the Azovstal plant, the last major bastion of Ukrainian defense in the city. 
• Kherson: The military head of the south-central city of Kryvyi Rih said Sunday that Ukraine had observed preparations for a possible offensive by Russian forces from the Kherson region, adding defenses were being bolstered in the area. In televised remarks, Oleksandr Vilkul said Russian forces were "forming an offensive strike formation in our direction in the Kherson region." Vilkul said the Kryvyi Rih garrison was in a state of readiness and had defenses prepared.
• UN visit: UN Secretary-General Antonio Guterres “will be received by President Vladimir Putin” on Tuesday in Moscow, after having a working meeting and lunch with the foreign minister of Russia, the UN said. He is also expected to meet President Zelensky on Thursday in Ukraine, according to a UN spokesperson.
• Forcible deportation: Russia has forcibly deported Mariupol citizens to Primorsky Krai in Russia's Far East region, according to the Ukrainian Parliament Commissioner for Human Rights. Lyudmyla Denisova said volunteers told her a train arrived in the city of Nakhodka on April 21 with 308 Ukrainians from Mariupol, including mothers with young children, people with disabilities and students.
• Russia's onslaught: An adviser to President Zelensky's administration said Sunday that Russia was "trying to depopulate the east of Ukraine," amid heavy fighting there. Earlier this week, Russia revealed that the goal of its invasion of Ukraine is to take "full control" over southern Ukraine as well as the eastern Donbas region, which has been the front line of the country's conflict with Russia since 2014.
