Russian strikes killed at least 12 people in Ukraine, local authorities have said, after Moscow pummelled its neighbour in overnight attacks.

Missile and drone attacks on the southern port city of Odesa killed six people, the head of the city’s military administration, Sergiy Lysak, wrote on Telegram on Thursday.

Strikes on the capital Kyiv killed at least four people, including a 12-year-old, the state emergency service of Ukraine said, while another two people died in the central city of Dnipro, according to Oleksandr Ganzha, the head of the regional administration.

Ganzha said earlier that the attack had wounded 10 people, including a 40-year-old woman who had been taken to hospital “in a serious condition”. It was not immediately clear if the woman was the person reported dead.

Rescuers in Kyiv pulled a child from the rubble of a residential building that collapsed in the Podilsky district, said the mayor of Kyiv, Vitali Klitschko. The attack on the capital wounded at least 10 people, including several medics, he added.

A blaze broke out at a building in the capital’s Obolonsky district where missile debris fell and cars caught fire, Klitschko said.

Tymur Tkachenko, the head of Kyiv’s military administration, warned civilians to shelter until a missile alert was lifted.

A drone strike on the north-eastern city of Kharkiv also wounded a 77-year-old woman and a 66-year-old man, the head of the regional military administration, Oleh Syniehubov, said on Telegram.

Moscow has fired hundreds of drones on its neighbour almost nightly since the beginning of the four-year war and recently expanded daytime strikes.
