Russia launched one of its biggest air attacks on Kyiv overnight, officials said, using more than 300 drones and seven missiles in strikes that also hit other parts of the country.

Four more people were injured in the five hour-long attack on the capital that hit seven of the city’s 10 districts, according to Vitali Klitschko, Kyiv’s mayor.

A Telegraph journalist was holed up in an air raid shelter and heard the buzzing of drones, followed by explosions and blaring air raid sirens throughout the night.

In the southern port city of Odesa, a maternity hospital and residential buildings were also hit, killing two people and injuring nine, local authorities said.

Condemning the attacks, Andriy Yermak, Volodymyr Zelensky’s chief of staff, said: “You can’t break Ukrainians with terror.”
