Feb 24 (Reuters) - Falling debris from destroyed

Ukrainian drones sparked a fire at an industrial enterprise in

Russia's Ryazan region, the governor of the region southeast of

Moscow said on Monday.

"According to preliminary information, there were no

injuries, material damage is being assessed," Governor Pavel

Malkov said in a post on the Telegram messaging app.

reported that Ukrainian drones targeted the Ryazan oil refinery,

which is owned by Rosneft.

not independently verify the Baza report.
