Russian rebels carried out a devastating attack on a rail line, causing a derailment of twenty carriages.
The incident happened on November 3 in Bashkortostan, on a segment of the track between Dema and Chernikovka.
An explosive device was placed under the carriage of a goods train that was transporting coal.
Following the explosion, twenty-two carriages were derailed, blocking the line for hours afterwards.
Russian police have arrested a 31-year-old man from the Stavropol region in connection with the attack.
Identified only as Ivan I, the suspect is under investigation for causing acts of sabotage.
Russian railway lines have frequently been targeted by partisans, since Putin’s full-scale invasion of Ukraine in February 2022.
Rail relay cabinets have been set on fire on numerous occasions, causing major disruptions to trains.
The attacks on transport infrastructure are part of a wider strategy by the internal Russian resistance to downgrade Putin’s war machine.
The Kremlin generates billions of pounds for its war in Ukraine through its sales of fossil fuels.
Some of the biggest buyers of Russian coal are India and China, who also import large quantities of the Kremlin’s oil and gas.
Roman Popkov, a leader of Rospartisans group told the Express in a previous interview that attacks on infrastructure inside Russia were essential to stop the war.
“A war on communications, on infrastructure and the industrial capacity of the terrorist state, is as important as the action on the front because the Empire will adapt to frontline conventional warfare as it has a lot of resources,” he said.
“But strikes on the home front, on the vulnerable places, it’s harder for it to adapt.
“So this is our goal, the maximum reduction of Putin’s military potential so that it will be more and more difficult for him to fight so that all this begins to fall apart gradually.”
Popkov, 45, is a former leader of the radical National Bolshevik Party and was a prominent anti-Putin activist in Russia well before the war.
