Russian strikes killed one person and wounded at least seven others in Ukraine, authorities said on Sunday, while Moscow officials reported downing more than 100 drones heading towards the capital.
Russia has increasingly been using long-range missiles in its war against Ukraine, while Kiev has responded with drone strikes deep inside Russian territory, including repeated attempts to target the capital.
A woman was killed and six people wounded in a combined ballistic missile and drone attack on Kryvyi Rig, the hometown of Ukrainian President Volodymyr Zelenskyy, according to the regional governor.
The city was under a "combined ballistic missile and drone attack", local defence council head Oleksandr Vilkul said earlier on Telegram, warning residents that further waves could follow.
Russian forces struck two industrial sites in the city, prompting rescue and firefighting operations, Vilkul said.
In Kiev, authorities issued an air raid alert shortly before 2:00 am (2300 GMT), warning of a ballistic missile threat.
AFP journalists in the capital heard several explosions shortly after.
Mayor Vitali Klitschko said Kiev was "under ballistic missile attack" and urged residents to remain in shelters.
Ukraine kills three in Russia
On the Russian side, a massive Ukrainian drone assault targeted the Moscow region and southern Russia overnight, leaving three dead and four wounded, Russian officials said on Sunday.
Moscow Mayor Sergei Sobyanin said air defences downed 201 of 600 drones heading toward the capital region, where three people were injured near the MKAD ring road.
In the southern Rostov region, Governor Yuri Sliusar said three people were killed, one was hospitalised, and over 150 drones and missiles were destroyed across three cities and nine districts.
The attacks damaged residential and industrial buildings, as well as a railway station in Rostov's Kamensky district, according to local authorities.
