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.

A top Russian pro-war blogger has been killed in a bomb attack on a cafe in Russia, according to police.

The explosion on Sunday tore through a cafe in St. Petersburg, killing Vladlen Tatarsky, one of the best-known of the Russian military bloggers who have become influential during the war in Ukraine.

At least 30 other people were injured in the blast, according to the Ministry of Health. Video circulating online appeared to capture the aftermath, showing bloodied people emerging from the heavily damaged cafe.

The Russian Interior Ministry said an explosion has occurred in a cafe on the city's Universitetskaya Embankment.

"One person was killed in the incident, it was military correspondent Vladlen Tatarsky, the Russian Interior Ministry press center told reporters on Sunday.

Denis Pushilin, acting head of the Russian-backed Donetsk People’s Republic, issued a statement describing Tatarsky as "a great patriot" of the Donbass region of eastern Ukraine and Russia. Pushilin blamed the attack on the Kyiv regime, calling it a terrorist regime.

"A man with a difficult fate, Vladlen earned the respect of his comrades-in-arms because he lived and worked for the sake of truth and justice, for the sake of victory," Pushilin said of Tatarsky. "He managed to fight, and in the status of a military correspondent to make his contribution."

Pushilin said Tatarsky was to be awarded a medal "for the liberation of Mariupol" in eastern Ukraine.

It was the most serious bomb attack on a pro-war Russian figure inside Russia since the high-profile assassination of the Daria Dugina, the daughter of the ultra-nationalist Alexander Dugina, who was killed in a car bombing last year.

Tatarsky was a Russian ultra-nationalist and one of the best-known military bloggers, who strongly supported the war in Ukraine. He had also criticized the execution of the war by Russia’s military command.

Tatarsky had become a significant source of information for how the war was being fought on the Russian side.

His killing will likely set off speculation on whether Ukraine or Russia was behind his killing, similar to the Dugina episode.

In the Dugina case, U.S. intelligence sources eventually told The New York Times that Ukraine was behind the attack.
