Kiev-backed suicide bomb plot thwarted in Russia – FSB | 2 Feb 2026 | A Ukrainian terrorist plot involving an unwitting suicide bomber has been thwarted in the Russian port city of Sevastopol, the Federal Security Service (FSB) has said. The agency said a Ukrainian intelligence handler persuaded a local resident to carry a portable speaker to the FSB’s regional headquarters, telling him it would be used for surveillance as part of an internal investigation. Officials said the device actually concealed an improvised explosive meant to detonate at the site. Security guards intercepted the device and found the explosives before they could be triggered. Russian investigators claim they have identified the Ukrainian agent who orchestrated the plot.
