An explosion early on March 4 damaged a railway bridge in Russia’s south-central Samara region, causing Russian authorities to suspend traffic on the line. The Baza Telegram channel reported that the explosion was caused by an improvised explosive device. No one was reported injured in the blast. Ukraine’s military intelligence wrote on Telegram that the bridge was disabled by an explosion and will be “impossible to use for a long time.” The agency added that the rail line was used to transport military supplies, particularly ammunition produced by a factory in the Samara region city of Chapayevsk.
