Russia unleashed a massive combined attack on Kyiv early Friday, sparking fires and scattering debris across many districts of the capital, mayor Vitali Klitschko said. At least 11 people were injured as emergency crews responded to multiple strikes, he said in a statement.

Five people were hospitalised, including one man in critical condition and a pregnant woman, after a series of powerful explosions sounded in the city and air defences were activated.

The attack on the capital was ongoing, officials said, urging residents to remain in shelters until the air raid alert is lifted. City authorities warned that power and water outages were possible.
