Multiple religious leaders, Chicago's Ukrainian community and supporters gathered on Monday night to mark an anniversary to a war they are praying will end.

Ukraine has the right to its existence and its self-determination," Cardinal Blase Cupich told hundreds gathered at Holy Name Cathedral to pray for peace and honor the dead at the three-year mark of war.

Ukraine's ambassador to the UK Valerii Zaluzhnyi was among the attendees of the hourlong service. The anniversary was marked as U.S. policies on Russia and Ukraine shift dramatically under President Donald Trump.

As the administration in Washington grows critical of Ukraine at the third anniversary of the Russian invasion, hundreds clad in Ukrainian colors and waving flags fill the Wrigley Building plaza downtown Saturday to call for strong support for Ukraine and an end to the war.
