Russian missiles and drones hammered Kyiv on Tuesday morning, officials said, in what appeared to be a large-scale attack on the Ukrainian capital and other cities the day after President Vladimir V. Putin of Russia promised to retaliate for a Ukrainian assault on a Russian city.
The Ukrainian Air Force said that the barrage involved some of Russia’s most powerful weapons, including hypersonic missiles that fly at several times the speed of sound. Air-raid alerts sounded constantly in Kyiv on Tuesday morning, as wave after wave of missiles rained down.
One person, an older woman, died in the attack, and 27 people were injured, including two children, according to Vitali Klitschko, the city’s mayor.
Loud bangs jolted the capital as its air-defense systems tried to shoot down the missiles. Massive plumes of black and white smoke rose throughout the city, cutting through the gray early-morning sky, as several buildings were hit.
Mr. Klitschko said that debris from intercepted strikes had caused fires in several areas and that power had been cut off from several residential buildings and other facilities. Mr. Klitschko added that a large warehouse had caught fire and that at least 16 people had been injured after a high-rise building was hit.
Kharkiv, Ukraine’s second-largest city and near the border with Russia, also came under a large-scale missile attack, according to Oleh Syniehubov, the head of the regional military administration there. At least one person was killed and 41 were injured, he said.
The attacks were launched hours after Mr. Putin had vowed to respond to what Moscow said were Ukrainian strikes on Saturday that killed 24 people in the Russian city of Belgorod. “From our side, we will build up the strikes,” Mr. Putin said on Monday.
A day before the strike on Belgorod, Russia had launched one of its largest air attacks of the nearly two-year-old war against Ukraine. That assault on Friday killed at least 39 people, wounded about 160 others and hit critical industrial and military infrastructure as well as hospitals and schools, the Ukrainian authorities said.
The Ukrainian authorities had warned for months that Russia was likely to pound Ukrainian cities and target their infrastructure once the weather turned cold, in a repeat of last year’s winter campaign against the energy grid. Those assaults plunged Kyiv into cold and darkness in the winter months.
It was not immediately clear what, exactly, the Russian military was specifically trying to hit on Tuesday. But in the center of Kyiv, white smoke billowed near a thermal plant that has been targeted in the past, and the local authorities reported damage to a water supply system in one neighborhood.
Over the past year, Ukraine has received powerful air-defense systems from its allies, including Patriot surface-to-air missile batteries, which have proved successful at repelling many Russian attacks.
Though Ukraine is well supplied with Western weapons, the surface-to-air missiles that are needed to intercept Russian missiles are in short supply. And with a front line more than 600 miles long, important air defenses need to be evenly distributed to protect Ukrainian troops from Russian attack helicopters and jets.
This has left Ukrainian forces in a difficult position as they juggle resources, trying to ensure that the front line and major cities such as Kyiv, Kharkiv, Dnipro and Lviv have sufficient resources.
Ukrainian officials warned in the fall that Russia had stockpiled more than 800 high-precision weapons in preparation for massive winter assaults.
In the attack on Friday, Russian missiles slipped through Ukraine’s air defenses thanks to a complex barrage that included hypersonic, ballistic and cruise missiles, as well as drones. The deluge Tuesday morning may have been intended to repeat that strategy.
