On 20 November 2024, the Danish Navy tracked a Chinese cargo ship after undersea internet cables were damaged in the Baltic Sea, causing major connectivity disruptions and raising sabotage concerns.
On November 20th, 2024, critical internet cables in the Baltic Sea near the Danish island of Bornholm were damaged, resulting in connectivity outages in the Baltic states and parts of Scandinavia. In response, the Danish Navy began closely shadowing a Chinese cargo ship operating in the vicinity, raising suspicions of possible intentional sabotage though no official confirmation was released. The Danish Defence Ministry publicly stated that increased naval presence aimed to ensure maritime security and monitor the suspicious vessel. This event amplified geopolitical tensions in the region due to the strategic importance of undersea cables for communication and data flow. The incident is under ongoing investigation as officials consider the possible implications of hostile actions targeting infrastructure.
Confidence: High
Classified as an aggressor event because the incident involves suspected hostile activity potentially targeting critical infrastructure by a Chinese vessel closely monitored by Danish forces. It is also classified as a defense preparation event because the Danish Navy undertook security measures to shadow the vessel and ensure safety of the maritime environment. Official confirmation of the naval escort and suspicions of sabotage support high confidence.
