[3] There have been many notable arson attacks on military recruitment offices in Russia since the beginning of the war,[4] and there has been speculation that some of the fires or explosions have been the result of sabotage efforts by Russian partisans[5] (such as Svoboda Rossii or Atesh partisan legion)[6] or Ukrainian saboteurs.
[7] A "yellow" (medium) terrorist threat level was introduced[8] in Bryansk, Kursk, and Belgorod oblasts, as well as some districts of Voronezh Oblast, Krasnodar Krai, and northern Crimea.
Starting from the end of March, a series of incidents and explosions were reported in border regions of Bryansk, Kursk, Belgorod, and Voronezh Oblasts.
[ru 1][9][10] The Ukrainian side refused to confirm or deny involvement in incidents at strategic locations.
[12][13] In May, a series of incidents on railway lines in Russia impeded the deployment of troops and military equipment to Ukraine; responsibility for these incidents was claimed by the Internet movement "Stop the Wagons"[ru 2] (a reference to the Russian anti-war slogan "Stop the War").
