Russia's Investigative Committee says it has arrested a Russian-Italian citizen suspected of bombing a freight train in the Ryazan region last month. The man, whose identity was not disclosed, allegedly detonated an improvised explosive device that damaged 15 freight train cars on November 11, the committee said on its Telegram channel. It said the man, 35, was a resident of Ryazan who had been recruited by Ukrainian intelligence in February last year and underwent "sabotage training" in Latvia. The message said the man had "confessed" to the bombing during an interrogation. Ukraine has not commented and the claim could not be independently confirmed.
