Ukrainian cities hit by 18-hour Russian air assault

Ukrainian cities have been hit by a relentless 18-hour Russian air assault – which authorities say is the largest single attack of the war. At least 31 people have been killed by more than 120 missiles – at least one of which entered the airspace of neighbouring Poland. The attack was designed to overpower Ukraine’s air defence system, and was immense and indiscriminate. Russia’s aerial assault may signal the beginning of a major winter offensive. Russian troops have now seized territory in key locations on the eastern front, while the Ukrainians remain under increasing pressure on the battlefield and in the air.
