Russia launched an attack on Odesa early Wednesday, the second night in a row the southern port city has been targeted.
Ukraine's air defenses were repelling a Russian attack, a spokesperson for Ukraine's Odesa military administration said.
"More Kalibr (cruise missile) launches have been documented from the Black Sea," spokesperson Serhiy Bratchuk said on Telegram.
A CNN team in Odesa witnessed a sustained barrage from the air defense near the direction of the port. The team also heard at least three large bangs.
Oleh Kiper, head of the Odesa region's military administration, urged people not to come close to windows.
"Do not approach the windows, do not film or show the work of air defense forces," Kiper said on his Telegram page Wednesday. "All residents of Odesa Oblast take shelter!"
Russian forces launched airstrikes on Odesa on Tuesday in retaliation for Kyiv's attack Monday on the strategic and symbolic Crimean bridge linking the annexed peninsula to the Russian mainland.
