Ukraine was behind the operation that caused an explosion on a major gas pipeline in the city of Langepas, Russia’s Tyumen Oblast, a source in Ukraine’s military intelligence agency (HUR) told the Kyiv Independent on July 11.
According to the source, the incident destroyed a section of the key pipeline supplying Russian military-industrial facilities in Chelyabinsk, Orenburg, and Sverdlovsk oblasts.
Langepas is located in western Siberia, some 3,000 kilometers (1,800 miles) from the Ukrainian border.
The explosion reportedly led to a large fire, with immediate damages estimated at $1.3 million.
Repairing and testing the pipeline could take about a month, the source said. Due to damage in a swampy area, repairs will be challenging, reducing gas supply by 25 million cubic meters and causing indirect losses of nearly $76 million, the source in HUR added.
The Kyiv Independent could not verify these claims.
Ukraine regularly strikes military targets deep within Russian territory in an effort to diminish Moscow's fighting power.
A similar incident was reported on July 5 in Russia's Vladivostok. Explosions damaged a gas pipeline and destroyed a water pipeline supplying military facilities in the region, a source in HUR told the Kyiv Independent.
