During his annual Victory Day speech in Moscow's Red Square on Tuesday, Russian President Vladimir Putin claimed that the Ukraine war was "unleashed" on Russia and blamed "Western global elites" while calling Ukrainian President Volodymyr Zelenskyy a puppet.

Putin also directly compared his ongoing war in Ukraine to the Soviet Union's victory over Nazi Germany in 1945, which is what Victory Day commemorates. He claimed that Russia "once again" was fighting for "civilization" and he painted a topsy-turvy picture that Moscow wants peace with all nations.

"Today, the civilization is once again at a decisive, turning point and an actual war has been unleashed against our homeland again," Putin said. "But we fended off international terrorism, we will protect residents of Donbas too and ensure our security."

Putin's speech made clear once more that the Russian president has no intention of negotiating currently or scaling back his ambitions to defeat Ukraine.

However, the Victory Day military parade in Moscow was a significantly shrunken version of itself on Tuesday, compared with previous years, due to Russia's huge losses in Ukraine and its urgent need for equipment. There appeared to be approximately 50 military vehicles taking part in this year's event compared with 130 during the 2019 parade. Tuesday's parade was also comprised of nearly all high armored vehicles, similar to Humvees.

The flypast part of the event, which usually involves helicopters and fighter jets, was cancelled on Tuesday despite clear, sunny skies in the Russian capital. But perhaps what was most notable was the cancelling of the parade in at least 24 Russian cities due to security concerns that Ukrainian forces might be able to strike them, likely because of Russia's shortages of troops and equipment.

Air raid sirens went off across Ukraine around 5 a.m. local time Tuesday.

Air defense systems were activated in the Kyiv region.

The Russian airstrike on Kyiv was the "fifth air attack" on the capital since the beginning of May, the Kyiv City Military Administration said on Telegram.

Four people were injured from falling debris after a Russian drone was shot down above Kyiv, Mayor Vitali Klitschko said on Telegram.

Three of the people injured were at the site of the explosion in Solomyanskyi district of Kyiv, and one was in the Svyatoshynskyi district of Kyiv, where wreckage fell on a residential building, the mayor added.

Debris also fell on runway at the Zhulyany airport in the Solomyansky district of Kyiv, the head of the Kyiv City Military Administration Serhiy Popko said on Telegram.

In Odesa, Russian troops launched a missile attack from strategic aircraft, Ukrainian Operational Command South said on Facebook. The X-22-type rockets used by the Russians were "aimed at one of the food companies and recreational zones on the Black Sea coast," the Operational Command South said.

Rescue services are working to put fires out, and no information about the number of people injured was immediately available, they added.

Two Americans have died while volunteering to fight in Ukraine, the U.S. Department of State said Wednesday.

Edward Wilton and Grady Kurpasi died in combat during the conflict, bringing the total number of Americans killed to at least eight.

Wilton, 22, died on April 7 fighting in Bakhmut, his half brother Parker Cummings told ABC News. He was from Marianna, Florida.

Wilton served in the U.S. Army, Cummings said, and informed his half brother about his plans to fight in Ukraine through a message sent from a plane en route to Poland on April 10, 2022.

“My brother was very selfless. My brother was very honorable and traditional," Cummings told ABC News. "He cared more about freedom for all than for his own safety. Edward was a true hero and he will be missed until we see him again.”

Joshua Cropper, who told ABC News he fought with Wilton in Ukraine’s International Legion between April and early July 2022, said of Wilton: “He was so young, but immensely brave. Fearless. We’d need three guys to do any task, he's always going to have his hand up. He was as mature as anybody I've ever known.”

Kurpasi was reportedly last seen in April 2022 and was widely reported to be missing last June.

As recently as last fall, his family said they believed he was in critical condition in a Russian-controlled hospital in Donetsk, but it’s not clear exactly when he was confirmed dead or if he was ever hospitalized.

A GoFund Me page organized on behalf of Kurpasi's wife provides few details on his time in Ukraine, but states that he “ended up leading a squad into battle and was killed in action.”

“We can confirm the death of a U.S. citizen in Ukraine. We are in touch with the family and providing all possible consular assistance,” a State Department spokesperson said in a statement when asked about his case. “When a U.S. citizen dies overseas, including in Ukraine, the Department of State supports the legal representative and family of the deceased in numerous ways, including by providing information on the disposition of remains and estates and issuing a consular report of death.”

The spokesperson added: “The U.S. government takes its role in such a situation very seriously, providing all appropriate assistance through the legal representative, next of kin or their designee.”

Regarding Wilton, a State Department official confirmed that a U.S. citizen died near Bakhmut and said they're in touch with the family and providing all appropriate consular services.
