Ukrainian President Volodymyr Zelenskyy, in an Easter message Sunday from Kyiv, called on Ukrainians to unite in prayer for each other and soldiers on the front line, saying God has a "Ukrainian flag on his shoulder."

"Let's pray for each other. When we all came closer to each other, we were no longer strangers to each other," he said in a video posted on Telegram. Standing in front of the 1,000-year-old Saint Sophia Cathedral in Kyiv, Zelenskyy noted that Ukraine has now been fighting for 802 days against Russia.

In Moscow, President Vladimir Putin attended an Easter service led by the head of Russia's Orthodox Church, Patriarch Kirill, a staunch supporter of the Russian leader and Russia’s war in Ukraine.

Eastern Orthodox Christians usually celebrate Easter later than Catholic and Protestant churches, because they use a different calendar and methodology for calculating the anniversary of what they believe is Christ’s resurrection.
