Russia said on Sunday that Ukraine launched a major 62-drone attack on Russian regions forcing one oil refinery in southern Russia to halt operations, and that Kyiv’s forces had fired US, French and Ukrainian missiles at Russian-held territory.

Russia shot down at least 103 drones, including 62 over Russian regions, as well as Army Tactical Missile System (ATACMS) over Crimea, French guided “Hammer” bombs and US High Mobility Artillery Rocket System (HIMARS).

Local officials said six drones crashed onto the territory of an oil refinery in Slavyansk in Russia’s southern Krasnodar region. Interfax news agency said the refinery halted work after the attack.

TASS quoted an official at the refinery as saying the charges carried by the Ukrainian-launched drones were bigger than previous attacks and that they included steel balls.

Slavyansk refinery is a private plant with a capacity of 4 million metric tonnes of oil per year, about 1 million bpd.

A Ukrainian intelligence source told Reuters in Kyiv that Ukraine’s security service SBU and military drones struck the Slavyansk refinery and a military airfield in Russia’s southern Krasnodar region in overnight attacks.

The Ukrainian navy also said it had destroyed the Russian Black Sea Fleet’s Project 266-M Kovrovets minesweeper.

Russia said its forces had defeated Ukraine’s 24th and 42nd mechanised brigades and the 125th Air Defense Brigade at Lukiantsi, Vesele and Radhospne in the Kharkiv region and repelled attacks by Kyiv’s forces at other points in the region.
