Russian missiles hit Ukraine's two largest cities, killing 18 people, injuring more than 130 and damaging homes and infrastructure, Ukrainian President Volodymyr Zelenskyy said.

The eastern city of Kharkiv suffered three waves of attacks. There were strikes on Kyiv and in central Ukraine and the southern region of Kherson, subject to constant shelling.

Zelenskyy, in his nightly video address, said Russia had launched nearly 40 missiles of different types in "another combined strike to try to circumvent out air defense system".
