Vladimir Putin has not commented but Dmitry Peskov, the Kremlin spokesman, said the Russian president had been informed of the attack and was in “constant contact” with his senior military, emergency and health care staff.
Many Russian tourists have shrugged off the dangers of Ukrainian missile attacks to take advantage of discounted package holidays to Crimea, famed across Russia for its golden beaches, clear water and blue skies.
At the time of the attack, the popular beaches outside Sevastopol, the biggest city in Crimea, were crowded at the start of the holiday season with families and children.
‘I had eight wounded’
Irina Frolova was swimming in the pool of a nearby hotel when she heard the Russian air defence systems hit the Ukrainian missile, followed by screams from the beach.
She said she rushed her children to their hotel room and then ran down to help.
“I went to the beach because I’m a medic,” she told the Izvestia newspaper. “There were a lot of wounded people there and by the time I arrived, they had already been taken off the beach to the parking lot. I had eight wounded people.”
Ms Frolova then described how a woman died in front of her. “There were mostly shrapnel wounds, a woman was hit in the neck by a double shrapnel. She died,” she said.
Concerns in Washington
Ukraine frequently targets Sevastopol, the main base for Russia’s Black Sea Fleet, but it usually fires its missiles at night and not in the middle of the day.
Russia’s Ministry of Defence said that the missile attack on Sunday had occurred just after midday. Ukraine has not commented but the strike will reignite concerns in Washington about relaxing rules it has laid out to Ukraine over how it uses US-made kit to hit Russia.
Ukraine wants to be given more freedom to strike targets deeper in Russia but Washington is concerned this will escalate the war.
Washington considers Crimea, annexed by the Kremlin in 2014, to be part of Ukraine and allows Ukrainian commanders to strike it with US-made missiles.
