Late last week, the Sakhalinskaya GRES-2 power station, a vast 120-megawatt coal-fired power plant in Russia’s far-eastern Sakhalin province, went up in flames, giving rise to persistent rumors of sabotage. On May 1, Russian state-owned news agencies reported that a railway bridge in the western province of Kursk, 70 miles from the Ukrainian border, had been destroyed. Analysts at the Washington-based Atlantic Council think tank claimed that the bridge had been used extensively by the Russian military to transport equipment to eastern Ukraine. Later on the same day, a cluster of fuel-oil tanks in Mytishchi, a mid-size city located northeast of Moscow, were completely destroyed by a fast-spreading fire.

On May 2, a munitions factory in Perm, a major urban center in western Siberia, was hit by a “powerful” explosion. Ukrainian government officials hinted at sabotage in social media posts, though no proof has been provided, and the Kremlin has not commented on the matter. On the following day, the Prosveshchenie publishing house warehouse in Bogorodskoye, northeast of Moscow, was destroyed by a massive fire. The warehouse belongs to Russia’s state-owned publisher of school textbooks. The fire occurred almost simultaneously as another fire engulfed a polyethylene waste storage facility in the central Siberian city of Krasnoyarsk.

Meanwhile, the sprawling forests that surround Krasnoyarsk and other Siberian urban centers are experiencing seasonal wildfires of near-unprecedented scale. Some early reports claimed that the Russian government was finding it difficult to contain these fires, because the country’s emergency response personnel has been sent to the frontlines of the war in Ukraine. But these reports were denied by Russia’s Ministry of Emergency Situations, which claimed earlier this week that the fires were mostly under control.
