Russia is "completely ignoring" a 30-day ceasefire proposed by Ukraine and European powers that was to have begun on Monday, Ukrainian Foreign Minister Andrii Sybiha said.

The announcement was made by leaders of Britain, France, Germany, Poland and Ukraine after a meeting in Kyiv, and a phone call with President Trump.

Ukraine and Russia are at odds over competing ceasefire proposals. Moscow has accused Ukrainian President Volodymyr Zelenskyy of threatening the safety of dignitaries attending Victory Day celebrations after he dismissed Russia’s unilateral 72-hour ceasefire.

Twangiza Mining, a gold miner operating in the rebel-controlled South Kivu Province in the eastern Democratic Republic of Congo, said it has been ordered to suspend operations by the rebel administration, according to a company-wide letter seen by Reuters.

After meeting in Kyiv on Saturday, Ukraine’s major European allies gave Russia an ultimatum: agree to an unconditional 30-day ceasefire in Ukraine by Monday or face “massive” new sanctions.

Moscow's self-declared truce which came into force at midnight on May 8 is not being felt on the front lines, Ukrainian soldiers have told the Kyiv Independent, reporting numerous cases of Russian military activity throughout the day.

French President Emmanuel Macron has warned of new sanctions on Russia if it refuses a ceasefire in Ukraine. The proposed measures would target Russia’s financial services and energy sector.

Ukraine and its European allies called on Russian President Vladimir Putin to agree to a 30-day ceasefire by Monday or face a new wave of sanctions.
