European and Ukrainian intelligence say Moran Security operatives have been placed aboard shadow-fleet tankers to conduct espionage and protect sanction-busting oil shipments, following earlier reports of covert Russian activity in Baltic waters.Intelligence and shipping records show some tankers added a small number of Russians listed as technicians in September while crews were mostly non-Russian, and French forces later boarded the sanctioned tanker Boracay off Brittany and questioned two Russians.Former Danish intelligence official Jacob Kaarsbo and Danish sea pilot Bjarne Caesar Skinnerup say the guards, some with Wagner links, appear to run ships onboard, and UK foreign intelligence chief Blaise Metreweli warned that Russia is testing NATO in the gray zone.
