© France 24 There is an ongoing NATO exercise taking place right now just off the south western coast of Estonia in the Gulf of Riga, and around the Baltic Sea stretching south to Skagan on the coast of Denmark. Exercise “Baltops”, with 20 ships, roughly 6,000 troops, and 16 countries taking part is usually one of the most significant NATO exercises of the year, and the oldest it started in 1972.
