NATO ships will start guarding critical locations in the Baltic Sea later this week, Finnish public broadcaster YLE reported on Wednesday.

A fleet of up to 10 NATO vessels will guard the infrastructure under the Baltic Sea until April, the Finnish broadcaster YLE reported on Jan. 7 after several cables were cut in suspected sabotage.

COPENHAGEN (Reuters) -Finnish police said on Tuesday they had recovered a lost anchor from the seabed as part of an investigation of suspected sabotage against power and internet cables in the Baltic Sea.

NATO will send about 10 ships to the Baltic Sea to protect underwater infrastructure, Finnish broadcaster Yle reported, citing sources. The NATO navy will begin arriving in the Baltic Sea at the end of the week and will remain there until April,

In addition, a U.K.-led 10-member consortium of northern European nations called the Joint Expeditionary Force (JEF) has reactivated an AI-based system to track suspicious ships in these waters. The actions are a response to the suspected deliberate severing on Christmas Day of the Estlink 2 undersea power cable and four undersea communications cables between Finland and Estonia,

NATO said on Friday it would boost its presence in the Baltic Sea after the suspected sabotage this week of an undersea power cable and four internet lines, while alliance member Estonia launched a naval operation to guard a parallel electricity link.

NATO allies met on Dec. 30 to address the security of critical infrastructure in the Baltic Sea, following damage to undersea cables connecting Estonia and Finland several days earlier.

General Mark Rutte says the military alliance will step up patrols in the Baltic Sea area as Finnish investigators work to establish whether a ship linked to Russia sabotaged undersea cables there this week.

NATO is deploying approximately 10 ships to protect underwater infrastructure in the Baltic Sea. The first of these ships is expected to arrive by the end of the week, and the operation will continue until April.
