Russian mystery fires

A series of unusual fires and explosions have occurred in Russia since the invasion of Ukraine in February 2022, which have not been formally explained. There have been many notable arson attacks on military recruitment offices in Russia since the beginning of the war, and there has been speculation that some of the fires or explosions have been the result of sabotage efforts by Russian partisans (such as Svoboda Rossii or Atesh partisan legion) or Ukrainian saboteurs.
