Several buildings have been hit in the attacks, Kyiv Mayor Vitaliy Klitschko said on Telegram.
Ukraine’s air defenses were put on alert overnight for incoming missile fire, and explosions were also reported in Zaporizhzhia.
The reports came after President Volodymyr Zelenskyy warned on Tuesday evening that a “massive attack” was expected, according to AFP. The attacks also coincide with Russian President Vladimir Putin’s 74th birthday.
