Volodymyr Zelenskyy says Ukraine is facing a "critical shortage" of air defence missiles from its partners, warning that delayed or slow deliveries were leaving the country more vulnerable to Russian attacks and contributing to civilian deaths and destruction.

At least eight people have been killed and more than a dozen wounded across Ukraine after a night of Russian strikes on the country.

Four adults and two girls aged five and 12 were killed by a ballistic missile that detonated in a house near the central city of Kryvyi. Eight other people were wounded in the attack, Kryvyi Rig's defence council reported, warning the death toll may rise.

"This Russian terror once again proves that protection against the Russian missile threat is the most important task when it comes to saving the lives of our people," Zelenskyy wrote on X.

"Untimely assistance and delays in the delivery of anti-ballistic missiles lead to this kind of destruction, these kinds of casualties that, unfortunately, we are seeing today."
