Swedish warships dropped depth charges and magnetic grenades in fog-bound Natfjarden Bay in an effort to find suspected foreign submarines spying on naval maneuvers, officials said. Warships, helicopters and frogmen later searched the area but by mid-afternoon had found no trace of submarines, defense staff spokesmen said. The navy operation began Friday when a patrol boat fired magnetic grenades at a suspected foreign submarine detected with sonar in Vidingefjarden Bay, 40 miles northeast of Stockholm.
