Russian missiles and drones hammered Kyiv on Tuesday morning, officials said, in a large-scale attack on the Ukrainian capital and other cities that killed at least five people and injured nearly 130 others, a day after President Vladimir V. Putin of Russia promised to retaliate for a Ukrainian assault on a Russian city.
The barrage — which the Ukrainian Air Force said involved about 100 missiles, including hypersonic weapons that fly at several times the speed of sound — was the latest in an escalating cycle of air assaults between the two countries, as both sides look for ways to inflict damage away from the largely deadlocked front line.
