Russian authorities have not yet provided official information on the extent of damage caused by the reported attacks.

The Yaroslavl refinery had already been undergoing repairs after being hit in a July strike, and it has been targeted at least eight times in 2026.

In Ukraine's Luhansk, a large hardware store was struck and set ablaze at the site where Ukrainian home improvement chain Epicentr once held a location before Russia occupied the city in 2024.

The city of Yaroslavl is located approximately 1,500 kilometers (900 miles) from Ukraine's border with Russia, while Ulyanovsk is situated around 1,200 kilometers (750 miles) from the border.

The Saratov refinery, which had previously halted operations several times, including after an August strike, was reportedly shut down again after a drone attack on September 11.

According to sources cited by Reuters, the Syzran refinery was shut down on September 15, while the Saratov refinery stopped operating on September 11, following recent Ukrainian drone attacks.

Overnight on September 15, Russia’s Volgograd and Samara oblasts reported explosions and fires at industrial facilities, including the Sebryakovcement plant and the Syzran refinery.

Independent Russian outlet Astra reported that on September 23, drones struck an area near an oil refinery in the city of Ufa, the capital of Russia's Republic of Bashkortostan, citing local residents.
