Overview

• The Estonian Navy attempted to detain the Jaguar, a tanker under British sanctions and suspected of being part of Russia's shadow fleet, near Naissaar Island on May 13.
• The tanker, sailing without a flag, refused to cooperate with Estonian authorities and was escorted to Russian waters without being boarded.
• A Russian Su-35 fighter jet entered NATO airspace for approximately one minute during the incident, leading NATO to scramble Polish MiG-29 jets as part of its Baltic policing mission.
• The Jaguar is now anchored near the Russian port of Primorsk under a Gabonese flag, highlighting ongoing challenges in enforcing sanctions on Russia's shadow fleet.
• Estonia has lodged diplomatic protests and called for tougher and faster sanctions, warning of escalating risks in the Baltic Sea as Russia shows willingness to defend its shadow fleet militarily.
