A Ukrainian F-16 fighter pilot died in a crash while repelling a Russian air attack that involved hundreds of drones, cruise and ballistic missiles, authorities said on Sunday, as Moscow intensifies night-time air barrages in the fourth year of war.

President Volodymyr Zelenskiy called for more support from Washington and Western allies to bolster Ukraine's air defences after the attack, which damaged homes and infrastructure across the country and injured at least 12 people, according to local authorities.

In Kyiv, families huddled in metro stations for shelter after air raid sirens rung out. Machine-gun fire and explosions were heard across the capital and in the western city of Lviv, where such attacks are less common.

The governor of the Lviv region, bordering Poland, said the raid targeted critical infrastructure.

Ukraine has now lost three F-16s since it began operating the US-made jets last year. Kyiv has not revealed the size of its F-16 fleet, but they have become a central and heavily used part of Ukraine’s defences.

The pilot flew the damaged jet away from a settlement but did not have time to eject before it crashed, the Ukrainian Air Force said.

“The pilot used all of his onboard weapons and shot down seven air targets. While shooting down the last one, his aircraft was damaged and began to lose altitude,” the Air Force said on Telegram.

The Ukrainian military said in total Russia launched 477 drones and 60 missiles of various types to Ukraine overnight. Ukrainian forces destroyed 211 of the drones and 38 missiles, it said, while 225 more drones were either lost due to electronic warfare or were decoys that carried no explosives.

"Moscow will not stop as long as it has the capability to launch massive strikes," Zelenskiy said on X. He said Russia had launched around 114 missiles, 1,270 drones, and 1,100 glide bombs just in the past week.

Russia's state-run RIA Novosti news agency said one person was killed by a Ukrainian drone in the Russian-controlled part of Ukraine's Luhansk region.

Wall Street extended its rally on Friday, sending the S&P 500 and Nasdaq to all-time closing highs - with each adding half a percent - while the Dow climbed one percent.

Both Ukraine and Russia say they do not attack civilian targets.

POLITICAL WILL

Ukraine says recent attacks highlight the need for further support from Washington, which under President Donald Trump has not committed to new military aid for Ukraine.

Trump said he was considering a Ukrainian request for more Patriot missile, opens new tab batteries after he met Zelenskiy at a NATO summit last Wednesday.

"This war must be brought to an end - pressure on the aggressor is needed, and so is protection," Zelenskiy said in his X post on Sunday after the attack. "Ukraine needs to strengthen its air defence - the thing that best protects lives."

He said Ukraine was ready to buy the American air defence systems and it counts on "leadership, political will, and the support of the United States, Europe, and all our partners."

Russia has launched large scale strikes on Ukrainian cities every few days in recent weeks, causing widespread damage, killing dozens of civilians and injuring hundreds more.

During the latest barrage, explosions were heard in Kyiv, Lviv, Poltava, Mykolaiv, Dnipropetrovsk, Cherkasy and the Ivano-Frankivsk regions, witnesses and regional governors said.

The Ukrainian military said air strikes were recorded in six locations.

Eleven people, including two children, were injured in the central Cherkasy region, the governor Ihor Taburets said on Telegram. Three multi-storey buildings and a college were damaged in the attack, he said. One woman was injured in western Ivano-Frankivsk region.

Rescuers evacuated residents from apartment blocks with charred walls and broken windows, images released by authorities in Cherkasy showed.

Industrial facilities were hit in the southern Ukrainian Mykolaiv and central Dnipropetrovsk regions, officials said. Railway infrastructure was damaged in Poltava city in the centre of the country.
