Does anyone know of the source for the claim that "roughly 10 deliberate undersea cable attacks occur each year?" @UKDefJournal doesn't offer a source.

Investigating the latest subsea cable cut in the Baltic (h/t @auonsson) Based on BGP, appears that Latvian State Radio and Television Centre's cable (AS8194) cable was cut at 00:45 UTC (2:45am local) on Sunday morning when it lost transit from Arelion.
