A MAJOR explosion hit a key Russian gas pipeline for the second time in ten months.

Footage caught the huge fireball from the blast on the Yamburg-Yelets 1 main supply pipe.

The glow from the inferno and smoke column were visible for several miles.

The cause of the explosion is being urgently investigated and comes amid a series of sabotage strikes on key Russian energy facilities linked to the war in Ukraine.

Kyiv rarely claims responsibility for such strikes.

The powerful inferno was near the village of Lykhma in the Khanty-Mansi region of Siberia, 300 miles north of capital Khanty-Mansiysk.

The pipeline supplies gas from the Yamal peninsula in northern Siberia to European Russia.

Reports said there were no casualties in the remote explosion.

The gas pipeline had to be cut, hitting supplies to European Russia.

Exports of gas by Russia have plummeted since the start of the war against Ukraine.

Two people were killed and three injured in a previous explosion on the same pipeline in May 2023.
