Destroyer HMS York spotted the vessel around ten miles inside the disputed “oil zone” around the South Atlantic islands.
The British crew had to radio the Argentinian ship, a smaller corvette named ARA Drummond, to demand that it change its course.
Sources told The Sun that the ship made an “innocent navigational blunder” and were embarrassed about the mistake. It is believed that the Drummond was spotted sailing alongside a French fleet before it broke away and headed for the disputed zone.
Under international law, the 15 miles of sea surrounding the Falklands are officially British waters
