July 9 (Reuters) - A Ukrainian drone attack spurred a

fire at a power substation and at an oil depot in Russia's

Volgograd region, the governor of the region in southern Russia

said on Tuesday.

"Air defence and electronic warfare forces suppressed a UAV

(unnamed aerial vehicle) attack on the territory of the

Volgograd region," Andrei Bocharov, the governor, said in a post

published on the Telegram channel on the region's

administration.

"As a result of falling UAV debris, fires broke out at a

substation in Frolovo and an oil depot in Kalach-on-the-Don."
