Ukrainian authorities issued air raid alerts for the entire country Wednesday, as Kyiv's air force warned of incoming cruise missiles.
"Kryvyi Rig -- take cover! A missile from the south is heading in your direction!" Ukraine's air force said in a post on Telegram, referring to central Ukrainian city.
It also warned of missiles headed towards the northern Chernigiv region, central Poltava region, and southern Mykolaiv region.
A "group of cruise missiles" was also headed in the direction of the capital Kyiv, it said.
The warnings come a day after Ukraine said it carried out its largest aerial attack on Russian territory of the nearly three-year war, hitting factories and energy hubs hundreds of kilometres from the frontline.
The Russian military accused Kyiv of using US- and British-supplied missiles for one of the strikes and promised it would "not go unanswered".
