On the night of Moscow’s preparations for a glitzy World War II victory memorial, Ukraine alleged a Russian strike on a school sheltering people claimed 60 lives. The G7 reiterated their alliance with Kyiv.

The fatality toll from Saturday’s Russian air strike on a school in the eastern village of Bilogorivka was verified by Ukrainian President Volodymyr Zelensky as the conflict continued. That would be the highest single-day death toll since Russia invaded on February 24.

Russia’s President Vladimir Putin is leading commemorations of the Soviet Union’s victory over Nazi Germany on Monday, but Ukraine is desperate to deny Moscow any sense of military virility.

During the symbolic event, Putin is expected to show off Russia’s military power. Huge intercontinental ballistic missiles will be towed into Moscow’s Red Square for official inspection, with fighter jets flying in a “Z” formation to signify support for the war.

The Victory Day parade has been a long-standing tradition in Russia, but this year’s version has grabbed centre stage as Putin tries to explain a conflict that has lasted considerably longer — and cost far more money — than intended.
