In a statement, the Navy states that it is the ocean patrol ship “Sines” that is accompanying the tug “Sergey Balk” and the submarine “Krasnodar”, in coordination with the branch's Maritime Operations Center.
Russian ships coming from the Mediterranean Sea will be monitored while they are in the Exclusive Economic Zone, the Navy adds in the statement.
The Portuguese Navy has accompanied several Russian ships since the beginning of the year, as they passed off the national coast - at least eight.
These missions have become more frequent since the start of the war in Ukraine on February 24, 2022.
In August, it accompanied, for example, the Russian ship “Kildin” and the “RFS Mercuriy”.
