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 hospitalized, including one man in critical condition and a pregnant woman, after a series of powerful explosions sounded in the city and airs defenses were activated.
