Russia fired more than 650 drones and three dozen missiles at Ukraine in a large-scale attack that began during the night and stretched into daylight hours Tuesday, officials said. At least three people were killed, including a 4-year-old child, two days before Christmas.

The barrage struck homes and the power grid in 13 regions of Ukraine, causing widespread outages in bitter temperatures, Ukrainian President Volodymyr Zelenskyy said, a day after he described recent progress on finding a peace deal as "quite solid."

The bombardment demonstrated Russian President Vladimir Putin's intention of pursuing the invasion of Ukraine, Zelenskyy said in a post on the Telegram messaging app. Ukrainian and European officials have complained that Putin isn't sincerely engaging with U.S.-led peace efforts.

The attack "is an extremely clear signal of Russian priorities," Zelenskyy said. "A strike before Christmas, when people want to be with their families, at home, in safety. A strike, in fact, in the midst of negotiations that are being conducted to end this war. Putin cannot accept the fact that we must stop killing."

President Trump has been pressing for a peace agreement for months, but the negotiations have become entangled in the very different demands from Moscow and Kyiv.

U.S. envoy Steve Witkoff said Sunday he held "productive and constructive" talks in Florida with Ukrainian and European representatives. Mr. Trump was less effusive Monday, saying, "The talks are going along."

Zelenskyy said the negotiations resulted in the preparation of "several draft documents" including ones on "security guarantees for Ukraine, on recovery, and on a basic framework for ending this war. The points ... have been set in such a way as to correspond to the objective of actually ending the war and the need to prevent a third Russian invasion."

Russian attack takes steep toll
Initial reports from Ukrainian emergency services said the child died in Ukraine's northwestern Zhytomyr region, while a drone killed a woman in the Kyiv region and another civilian death was recorded in the western Khmelnytskyi region, according to Zelenskyy.

Russia launched 635 drones of various types and 38 missiles, Ukraine's air force said. Air defenses stopped 587 drones and 34 missiles, it said.

It was the ninth large-scale Russian attack on Ukraine's energy system this year and left multiple regions in the west without power, while emergency power outages were in place across the country, acting Energy Minister Artem Nekraso said. Work to restore power would begin as soon as the security situation permitted, he said.

Ukraine's largest private energy supplier, DTEK, said the attack targeted thermal power stations in what it said was the seventh major strike on the company's facilities since October.

DTEK's thermal power plants have been hit more than 220 times since Russia's full-scale invasion began in February 2022. Those attacks have killed four workers and wounded 59.

Authorities in the western regions of Rivne, Ternopil and Lviv, as well as the northern Sumy region, reported damage to energy infrastructure or power outages after the attack.

In the southern Odesa region, Russia struck energy, port, transport, industrial and residential infrastructure, according to regional head Oleh Kiper.

A merchant ship and over 120 homes were damaged, he said.
