WASHINGTON - Following talks with US President Donald Trump and European leaders in Washington, Ukrainian President Volodymyr Zelensky said on Monday that security guarantees for Kyiv could be finalized within the next 10 days.

"Security guarantees will probably be 'unpacked' by our partners, and more and more details will emerge," Zelensky told a press briefing after the White House meetings, adding that detailed arrangements are expected to be formally documented within the next week to 10 days.

"It is important that the United States is sending a clear signal that it will be among the countries helping to coordinate and will also be a participant in the security guarantees for Ukraine," he said.

Trump told Zelensky on Monday that the United States would play a role in ensuring Ukraine's security as part of any agreement to end the conflict with Russia, without providing details.

He said Europe is the "first line of defense", but "we're going to help them out."

Zelensky said that part of the guarantees involves a US weapons package. "There indeed is a package with our proposals worth 90 billion US dollars," he said.
