Kyiv is working with allies on security guarantees akin to NATO's mutual protection pledge, Ukraine's president Volodymr Zelensky has said. Officials from Ukraine and allies the U.S., the U.K., France and Germany met in London on Thursday in a week when a peace proposal was produced which outlined an Article 5-like agreement which would be backed by Washington.

The president’s comments came after he said Crimea “will stay with Russia,” a position backed by the mayor of Kyiv, who conceded that his country may have to give up territory.

Moscow and Washington seem close to an agreement on a Ukraine peace plan, leaving Russia pleased – even if the talks don’t pan out.

A senior Central Intelligence Agency official’s son who had joined the Russian military was killed last year during an offensive in eastern Ukraine. The agency said it was a private tragedy and not a national security issue.

The Russian general died in a car bombing in the Russian city of Balashikha on Friday, according to authorities, with news of the blast breaking just before US President Donald Trump’s special envoy Steve Witkoff met with Russian leader Vladimir Putin in Moscow.

The Kremlin blamed Ukraine for a car bomb that killed a senior Russian military officer near Moscow on Friday, hours before U.S. President Donald Trump's envoy Steve Witkoff was due to meet President Vladimir Putin in Moscow.
