US army secretary briefs ambassadors at ‘nightmare meeting’ in Kyiv on Friday after talks with Ukrainian leader

US officials have told Nato allies they expect to push president Volodymyr Zelenskyy into agreeing to a peace deal in the coming days, under the threat that if Kyiv does not sign, it will face a much worse deal in future.

The US army secretary, Dan Driscoll, briefed ambassadors from Nato nations at a meeting in Kyiv late on Friday, after talks with Zelenskyy and taking a phone call from the White House. “No deal is perfect, but it must be done sooner rather than later,” he told them, according to one person who was present.

The mood in the room was sombre, with several European ambassadors questioning the content of the deal and the way in which the US had conducted the negotiations with Russia without keeping allies informed.
