iran gave the coordinates that they found the british ship in--and it was in iraqi waters! iran has since revised their coordinates, but it is not backed up by gps evidence.
the brits were in iraqi waters. iran is the one (again) who has entered another countrys area--i am assuming everyone heard about the gunfight between iranians and iraqis/us inside iraq a few weeks ago...
