Russian authorities said 11 people, including four children, had been killed by Ukraine in an overnight attack on a holiday camp, accusing Kyiv on Saturday of deliberately targeting civilians.

Ukraine did not immediately respond to a request for comment.

Russian-appointed governor Yevgeny Balitsky said another 16 people had been wounded in the attack on the resort area of Kyrylivka, which lies on the coast of the Azov Sea near the town of Melitopol.

"The enemy saw and understood who it was targeting," he said on the Telegram messaging app.

Ukraine strikes Russian oil targets

Ukraine said on Saturday its drones had hit a Russian oil platform in the Caspian Sea and an oil refinery in Siberia, while both Kyiv and Moscow said they had struck ships carrying military cargo.

Ukraine struck the Filanovsky oil platform belonging to Russia's Lukoil, its SBU security service said. Lukoil did not immediately respond to a request for comment. The platform is part of Russia's largest Caspian oil field.

Local authorities in the Siberian region of Tyumen confirmed that a Ukrainian drone had caused a fire at the region's refinery. They did not say if output had been disrupted.

Both sides have increasingly targeted shipping as they seek to derail military logistics and supply lines far from the battlefield.
