Russian President Vladimir Putin on Tuesday told his country's Victory Day parade on Moscow's Red Square that "a real war" has been unleashed against Russia by the West's "untamed ambitions," shortly after the Kremlin's forces rained cruise missiles on Ukrainian targets.

"Today civilisation is once again at a decisive turning point," Putin said at Moscow's annual commemorations celebrating the defeat of Nazi Germany in World War II. "A real war has been unleashed against our Motherland."

Since Russia invaded its neighbor more than 14 months ago, Putin has repeatedly framed the war in Ukraine as a proxy conflict with the West. The Kremlin's official narrative of the war has painted a picture of an existential conflict with the West, which in Moscow's view is merely using Ukraine as a tool to destroy Russia, re-write its history and crush its traditional values. That version of events has dominated Russian state media coverage of the war.

In his speech, Putin insisted that the West's "untamed ambitions, arrogance and impunity" are to blame for the conflict.

Putin welcomed soldiers fighting in Ukraine who were present at the parade. "To Russia! To our brave armed forces! To Victory!" Putin concluded the speech.

Russia unleashed a barrage of cruise missiles on Ukraine overnight into Tuesday, hours before the start of the Moscow parade, which this year is taking place amid tight security measures.

The Kremlin's forces launched 25 missiles overnight in a wave of attacks across Ukraine, the Ukrainian air force said, adding that air defense had successfully destroyed 23 of them.

In a Telegram post, the air force said eight Kalibr cruise missiles were launched from carriers in the Black Sea toward the east and 17 from strategic aircraft.

The barrage came as Moscow and other cities hosted military parades and other festivities marking Victory Day, Russia's biggest secular holiday that this year has been significantly overshadowed by the war in Ukraine.

At least 21 Russian cities canceled May 9 military parades the staple of celebrations across Russia for the first time in years. The Immortal Regiment processions, in which crowds take to the streets holding portraits of relatives who died or served in World War II another pillar of the holiday have also been canceled in multiple cities.

Regional officials blamed unspecified "security concerns." Some speculated, however, that the reason behind canceling Immortal Regiment marches was the fact that Russians might bring portraits of relatives who died in Ukraine to those processions, illustrating the scale of Russia's losses in the drawn-out conflict.

Moscow was expected to project a show of force during its flagship parade on Red Square, with top-notch military equipment rumbling through it and leaders of ex-Soviet nations standing beside President Vladimir Putin.

Initially, only one of them Kyrgyz President Sadyr Zhaparov was expected to attend, but at the last minute on Monday officials confirmed that leaders of Armenia, Belarus, Kazakhstan, Tajikistan, Turkmenistan and Uzbekistan were heading to Moscow as well.

The pared-down celebrations come after ambiguous official reports last week that two Ukrainian drones flew into the heart of Moscow under the cover of darkness and reached the Kremlin before being shot down. The Kremlin billed it as an attempt at Putin's life; Ukraine denied involvement.
