Five people have been killed in a Russian strike on a law school known locally as the “Harry Potter castle” in the southern Ukrainian port of Odesa, local officials said.

At least 32 others were injured in Monday’s attack with 23 of them still hospitalised on Tuesday.

Footage showed the roof of the ornate building, a private law academy, all but destroyed after the strike as firefighters battled the flames.

“Monsters. Beasts. Savages. Scum. I don’t know what else to say,” Gennadiy Trukhanov, the mayor of Odesa, said in a video posted on Telegram. “People are going for a walk by the sea and they are shooting and killing.”

Dmytro Pletenchuk, a spokesman for the Ukrainian navy, said the strike was conducted by an Iskander-M ballistic missile with a cluster warhead.

Regional governor Oleh Kiper said that in addition to those killed in the attack, one man died after suffering a stroke attributed to the strike.

Mr Kiper said on Tuesday morning that eight of the injured were in serious condition, and four in critical condition, including a four-year-old child. Another child and a pregnant woman were also among the injured.

“Our doctors are trying to do their best,” he added.
