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.

About 15 Russian missiles were launched at Kyiv and intercepted by the Ukrainian air defenses around Kyiv with "no casualties and major damage," the city military administration added.-ABC News' Yulia Drozd and Yuriy Zaliznyak

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.

A Moscow court has sentenced one of Russia's best-known opposition leaders, whose family live in the U.S., to 25 years in prison in what is widely seen a show trial.

Vladimir Kara-Murza is the most high-profile opponent of Russian President Vladimir Putin to be jailed since Alexey Navalny.

Kara-Murza's extraordinarily harsh sentence is one of the lengthiest any opposition figure has received under Putin and illustrates how repressive Russia has become during the war in Ukraine, reverting to something much closer to the USSR where no opposition is tolerated.

Kara-Murza was convicted of treason, as well as "discrediting Russia's armed forces," a new law that effectively criminalizes criticizing the war in Ukraine. He was also convicted of belonging to a banned organization. The charges are widely seen as politically motivated.

Kara-Murza is one of Russia's best-known pro-democracy figures and a veteran critic of Putin.

Kara-Murza, who holds both British and Russian citizenship, spent many years living in the United States and his wife and children still live in Virginia. He was close to the late U.S. Sen. John McCain, who championed human rights in the former Soviet Union.

Dozens of journalists and Western diplomats attended the court hearing on Monday, including the U.S. ambassador who read out a statement condemning the sentence.

"We support Mr. Kara-Murza and every Russian citizen to have a voice in the direction of their country. Mr. Kara-Murza and countless other Russians believe in and hope for a Russia where fundamental freedoms will be upheld. And we will continue to share those hopes and work for that outcome," Amb. Lynne Tracy said.

Kara-Murza previously has survived being poisoned not once but twice. In 2015 and then again in 2017, he suffered organ failure after being exposed to an unknown toxin. Independent researchers later linked the poisoning to the same team of FSB poisoners who targeted Navalny.

He chose to return to Russia after the war began, believing it was important to continue to campaign for freedom in his country and has been an outspoken critic of the invasion.

His trial was held entirely behind closed doors, but a letter containing his closing statement to the court has been released to reporters.

"I only blame myself for one thing," Kara-Murza said in the statement. "I failed to convince enough of my compatriots and politicians in democratic countries of the danger that the current Kremlin regime poses for Russia and for the world."

"Criminals are supposed to repent of what they have done. I, on the other hand, am in prison for my political views. I also know that the day will come when the darkness over our country will dissipate.
