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.

Just a week after the Pacific Fleet was ordered to stage surprise combat drills, Russian President Vladimir Putin fired the commander of the Russian Pacific Fleet, Sergei Avakyants.

Earlier, Putin praised the Pacific Fleet maneuvers and said that the Navy could be used "for the resolution of conflicts anywhere."

"He turned 65 on April 6. He is still on the Russian Defense Ministry's staff. With the consent of the Russian Defense Ministry, he will head a central body overseeing military sports and patriotic education centers, created on the orders of the [president]," the press service 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.

Russian airstrikes targeted several cities across Ukraine early Friday, killing at least 25 people, Ukrainian officials said.

The city of Uman in central Ukraine's Cherkasy Oblast was the worst affected. Several buildings were damaged or destroyed. One of the strikes hit an apartment building, killing at least 23 people, including four children, and injuring another 18 people, according to Cherkasy Oblast Gov. Ihor Taburets. The attack happened at around 4:30 a.m. local time, when most people would have been asleep. An entire section of the nine-story building collapsed, with 27 apartments completely destroyed. There were 109 people who lived in that part of the building, according to Ukrainian police. Rescue teams were expected to spend all day and night searching for survivors in the rubble.

It was the deadliest single attack on civilians in Ukraine since January.

Dnipro, Ukraine's fourth-largest city and a major industrial hub located in southeastern Dnipropetrovsk Oblast, was hit by "high-precision" strikes in the early morning hours, leaving a woman and a 3-year-old child dead, according to Dnipro Mayor Boris Filatov.

Russian strikes also targeted Kyiv, Ukraine's capital and largest city, but there were no reports of any casualties or damages. It was the first such attack on the capital in 51 days, according to the Kyiv City Military Administration. Preliminary data shows 11 cruise missiles and two drones were destroyed in Kyiv's airspace, the city military administration said.
