Sharjah24 - AFP: Russia intercepted 68 Ukrainian drones over seized Crimea and in its southern Krasnodar region during the course of Friday and Saturday.

The ministry said 66 of the drones were shot down over Krasnodar and the other two over the Crimean peninsula, which Moscow annexed in 2014.

"They tried to attack oil refineries and infrastructure. According to the information there, there are no injuries or serious damage," Krasnodar regional governor Veniamin Kondratyev said on Telegram.

Kyiv has stepped up drone attacks in recent months, in particular targeting Russia's energy infrastructure.
