Russian President Vladimir Putin appeared last week to be cautiously optimistic on the U.S. 28-point peace plan to end his invasion of Ukraine.

Top Trump administration officials are meeting Ukrainian negotiators in Florida this weekend, pushing to broker an end to Russia's war in Ukraine and setting the stage for key talks planned this week in Moscow with Russian leader Vladimir Putin.

Russia launched its largest barrage of drones and missiles in a month across Ukraine, killing at least three people, Ukrainian President Volodymyr Zelensky said Saturday, as a Kyiv delegation heads to the United States for fresh peace talks.

The attack came as U.S. officials were expected to hold peace talks with Ukrainian and Russian officials in the coming days.

"We need to sit down and discuss this seriously," Putin told reporters at the end of a three-day visit to Kyrgyzstan. He described U.S. President Donald Trump's 28-point peace plan as "a set of issues put forward for discussion" rather than a draft agreement.

Ukrainian anti-corruption authorities searched the apartment of Andriy Yermak, the influential top aide to President Volodymyr Zelenskiy as the country is reeling from a major graft scandal and coming under pressure in US-led peace talks.

US officials are meeting in Florida this weekend with their Ukrainian counterparts about the Russia-Ukraine war.
