Sweden plans to boost coast guard surveillance in Baltic Sea

"We have not chosen our external situation, but we must deal with the reality we face," Sweden's Minister for Civil Defence Carl-Oskar Bohlin said in a statement.

NATO, of which Sweden is a member, said on Saturday that it was upgrading its mission in the Baltic Sea with an air-defence frigate and other assets following supposed drone incursions in Denmark.
