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.

Russia has fired nearly 80 missiles at Kherson in 24 hours amid ongoing shelling, a local official said.

"For the previous day, we have recorded 79 shellings throughout our territory," First Deputy Chairman of the Kherson Regional Council Yuriy Sobolevskyi said on Telegram earlier Wednesday. "About 300 rounds of ammunition were used by the enemy."

At least two people have sought medical attention due to shelling injuries, according to Sobolevskyi, who noted that the "shelling continues."

Ukrainian President Volodymyr Zelenskyy said the Ukrainian counteroffensive will start before Ukraine receives F-16 fighter jets sought from Western countries.

"Frankly speaking, it would help us a lot. But we also understand that we can't drag it [the counteroffensive] out, which is why we'll start before we receive F-16 [aircrafts] or other models," Zelenskyy said at a news conference for Scandinavian media held in Kyiv on Saturday, according to a script provided by Reuters.

He added, "But to calm Russia down with the fact that we'd still need a couple of months to train on the aircrafts and only then we'd start; No, this won't happen. We'll start and go forward, while at the same time, simultaneously, I think this is very important [to receive western fighter aircrafts.]"

He said Ukraine is "capable of putting an end to this war."

Also on Saturday, Ukraine's Foreign Minister Dmytro Kuleba said Ukraine received a signal from some countries about the readiness to start training Ukrainian pilots on F-16 fighter jets.

According to Kuleba, the F-16 fighter jet is the ideal aircraft due to its technical characteristics, although Kyiv does not overlook other aircraft, either. The minister added that the decisive word on issuing F-16s will be with the United States, because these are American fighters.
