Four people are feared dead in the Marshall Islands after their empty boat was found half submerged in the open ocean.
A U.S. Navy C-130 aircraft that joined the search for the boat earlier yesterday sighted the craft yesterday evening in a vertical position.
The search is continuing for the three Marshall Islanders and one American who left Arno Atoll last Friday in a 13-foot outboard engine boat headed for the capital Majuro.
The boat was located about 16 kilometres south of Arno Atoll which is about 50 kilometres from the starting point of its journey.
The two atolls are about 25 kilometres apart.
