A Russian attack on Ukraine's southern city of Odesa on Monday struck civilian infrastructure and caused casualties, the region's governor said on the Telegram messaging app.
Ukraine's interior ministry published photographs of a massive cloud of smoke rising from the site where emergency services were working to put out a fire.
The Ukrainian air force had warned the city's residents of the threat of incoming missiles before the explosions sounded.
Odesa has been a frequent target of Russian forces in the 28-month-old full-scale invasion, with many attacks aimed at the city's port facilities. Russia denies targeting civilians or civilian infrastructure.
