Kyiv was the main target of an hourslong assault that killed at least two people, officials said. The barrage came hours before the top American and Russian diplomats met.

Russia launched a large-scale aerial assault on Ukraine’s capital Kyiv in the early hours of Thursday, marking a second consecutive night of ferocious attacks on the country, as Russia ramps up its bombardment more than three years into the war.

There is too little data to generate a comparable live estimate for Ukraine. However, a catalogue of the known dead and missing from UAL osses, a website, implies that between 73,000 and 140,000 Ukrainian soldiers have died since the invasion began.
