“European investigators increasingly see Russian fingerprints around recent acts of suspected sabotage on strategic infrastructure but are struggling to respond,” the Wall Street Journal reports.
“Reacting to clandestine threats is difficult because evidence around the suspected attacks—including a severed undersea gas pipeline, cuts in a vital internet connection and the disruption of a rail network—often isn’t conclusive. Potential culprits in big cases include commercial shipping or fishing vessels that have been engaged in apparently legitimate maritime transport or trawling for fish near sensitive seabed installations that were destroyed around the same time. They rarely have direct connections to Russian authorities, investigators say.”
