British Foreign Secretary David Lammy and U.S. Secretary of State Antony Blinken announced on Tuesday that they will travel to Kyiv this week to demonstrate their "commitment to Ukraine."

During a joint press conference in London, Lammy said: "Today, I can confirm that Tony and I will be traveling to Kyiv this week, the first joint visit of this kind for well over a decade."

"We are the closest of allies, so I'm delighted that we will travel together, demonstrating our commitment to Ukraine," he added.

For his part, Blinken also mentioned the planned trip, pointing out that it is "a critical moment" for Ukraine.
