Ammon News - An infant was among three people who died in Russia's overnight attacks on Kyiv that injured 18 and set on fire scores of buildings in the capital, including the seat of the government, Ukrainian officials said on Sunday.

Kyiv's Mayor Vitali Klitschko said a fire broke out at the government building in the city centre after the attack, which began with drones raining down, followed by missile strikes.

Reuters witnesses saw thick smoke rising from the building in the city's Pecherskyi district.

The drone attacks killed the infant and a young woman, Klitschko said on the Telegram messaging app, while a pregnant woman was among the five injured admitted to hospital.

Earlier Klitschko had said an elderly woman died in a bomb shelter in the leafy Darnytskyi district to the east of the Dnipro River, the site of the other two deaths.

Moscow did not immediately offer comment. Both sides deny targeting civilians in the strikes, but thousands have died in the war Russia launched with a full-scale invasion of Ukraine in February 2022.
