Multiple undersea cables and pipelines in the Baltic Sea have been damaged in recent months, raising suspicions of sabotage.

An undersea data cable between Latvia and Sweden was damaged early on January 26, the latest in a series of similar incidents in the Baltic Sea in which critical seabed energy and communications lines are believed to have been severed by ships traveling to or from Russian ports.

Intelligence officials in the U.S. and Europe have suggested that recent incidents damaging critical cables in the Baltic Sea were accidental, according to a Washington Post report. Western geostrategic self-deception has overly emphasized fears of escalation and cornering Russia.

The Nordic country has opened an investigation into the damage, just weeks after NATO stepped up its military presence in the area following a series of similar incidents.
