Odessa has seen increased attacks by Moscow in recent weeks.
A teenage boy was killed in a fresh Russian strike on Ukraine's Black Sea port of Odessa Monday, the southern city's council said on social media.
"As a result of a missile strike in Odessa, a residential building which had five people in it at the time of the attack, was damaged. A 15-year-old boy died," Odessa city council said on Telegram.
A girl was hospitalised, it said but gave no details on the other three people in the building.
The statement came after Ukraine said there was a new strike on Odessa.
"The enemy fired a missile at one of Odessa's infrastructure facilities," regional governor Maxim Marchenko said earlier on Monday.
"Unfortunately, there are dead and wounded," he said.
Odessa, a largely Russian-speaking city and cultural hub, has seen increased attacks by Moscow in recent weeks.
Late last month, five people were killed, including a three-month-old baby girl, in a Russian strike on the city.
Russia has regrouped its forces to attack Ukraine's south and east, where fighting is heavy.
