Russia is reportedly using fishing trawlers to spy on the UK's critical undersea cables, according to a recent analysis by The Telegraph. Over 500 incidents have been documented where these vessels loitered above or followed the routes of vital communications cables linking the UK with Europe and the US. This activity raises concerns about potential sabotage in future conflicts, as knowledge of the cables' precise locations could lead to significant disruptions in banking, healthcare, and telecommunications. NATO is monitoring these civilian ships, which appear to be operating without interference from the Royal Navy. The UK government is preparing to introduce tougher penalties for those who damage undersea cables, including lengthy prison sentences and unlimited fines. The Ministry of Defence has acknowledged the threat posed by Russian activities in UK waters and is increasing funding for the protection of critical infrastructure.
