NATO Secretary-General Jens Stoltenberg held a press conference with Ukrainian President Volodymyr Zelenskyy in Kyiv, to highlight the more than €150 billion of support to Ukraine since Russia launched its invasion.

"Allies are now delivering more jets, tanks, and armored vehicles, and NATO's Ukraine fund is providing urgent support," he said in a statement. "All of this is making a real difference on the battlefield today."

While in Ukraine, the secretary-general visited Bucha and paid his respects to the victims of Russian atrocities.

He also laid a wreath at the Wall of Remembrance of the Fallen for Ukraine, paying tribute to all those who have lost lives or suffered wounds in defense of their homeland.

"Ukraine’s rightful place is in the Euro-Atlantic family. Ukraine’s rightful place is in NATO. And over time, our support will help to make this possible," Stoltenberg said.

Anne Hidalgo, the mayor of Paris, which is hosting the 2024 summer Olympics, told Ukrainian President Volodymyr Zelenskyy that Russian athletes "cannot be accepted in Paris," if the war with Ukraine is still ongoing when the games begin.

"Paris is the capital of human rights," Hidalgo said in a statement. "We are trying to convince athletes, international federations and countries. We stand with you."

Hidalgo and Vasco Cordeiro, the president of the European Committee of the Regions, met with Zelenskyy as part of the International Summit of Cities and Regions Thursday.

Zelenskyy thanked Hidalgo for her support and presented her with Ukraine's "Rescuer City" honorary award.
