KYIV, Ukraine — Russia unleashed a nearly 10-hour air assault across Ukraine on Saturday, killing at least two people in the capital and injuring dozens more, according to Ukrainian authorities.

The attack, which involved dozens of Russian missiles and hundreds of drones, came as Donald Trump administration officials were expected to meet with Ukrainian and Russian officials in the coming days as part of a diplomatic push to end the war.

The Russian assault started just before midnight, with the capital, Kyiv, coming under the heaviest fire. The all-clear was given around 9:30 a.m. Under a thick white fog, emergency workers scrambled to respond to fires and tend to the wounded in seven districts of Kyiv.

The city’s mayor, Vitali Klitschko, said two people had been killed and at least 37 injured. A third person was killed outside the city.

Andrii Sybiha, Ukraine’s foreign minister, noted that the assault came as the Trump administration was trying to maintain momentum in the peace talks.

“While everyone is discussing points of peace plans, Russia continues to pursue its ‘war plan’ of two points: to kill and destroy,” Sybiha wrote on the social platform X.

President Volodymyr Zelenskyy of Ukraine said Russia had targeted energy infrastructure and “civilian facilities” in the attack, which involved 36 missiles and nearly 600 drones. More than 600,000 consumers were without power in Kyiv and the surrounding region Saturday morning, according to the country’s Energy Ministry.

U.S., Ukraine aides meet today

Top negotiators for President Donald Trump plan to meet with Ukrainian officials in Florida on Sunday to discuss a possible peace settlement to halt Russia’s invasion of Ukraine, according to a senior U.S. official.

The U.S. negotiators who plan to attend the talks are Secretary of State Marco Rubio; Steve Witkoff, a special envoy for the president; and Jared Kushner, the president’s son-in-law and a businessperson who does some international diplomacy for Trump.

The meeting follows a round of talks between those officials and Ukrainian negotiators last weekend in Geneva. In Kyiv, President Volodymyr Zelenskyy is grappling with the fallout from a corruption investigation that led to the resignation Friday of his top negotiator and chief of staff, Andriy Yermak. Yermak had participated in the Geneva talks and had appeared with Rubio to discuss them with reporters.

Russian officials said earlier that Witkoff planned to travel to Moscow this week.

The recent diplomacy has become fraught because of questions about whether some of Trump’s aides are favoring the demands of President Vladimir Putin of Russia at the expense of Zelenskyy and Ukrainians, whose country is besieged by the Russian military.

After Trump told them last month to make a push on resolving the war, Witkoff and Kushner drafted a 28-point proposal, incorporating Russian input. During the process, the two Americans met secretly in Miami with Kirill Dmitriev, an envoy for Putin who is in charge of Russia’s sovereign wealth fund.

The Americans also met in Florida this month with Rustem Umerov, the national security adviser to Zelenskyy. Umerov will be part of the Ukrainian group today,
