Explosions were heard in the capital, Kyiv. Power and water supplies in the city have been disrupted by the attack, Kyiv Mayor Vitalii Klitschko said.

hor Polishchuk, mayor of Ukraine’s western city of Lutsk, said a multi-story residential building and an unspecified infrastructure object were hit and one person was killed. Another person was killed in the central Dnipropetrovsk region, where the attack sparked multiple fires, regional head Serhii Lysak said. One person was also killed in the southeastern, partially occupied region of Zaporizhzhia, regional head Ivan Fedorov said.
