Claims by Rulers of Qatar and Abu Dhabi to island of Halul

This file contains correspondence relating to competing claims by the Rulers of Qatar and Abu Dhabi to Halul Island, which lies within the seabed concession granted to the Marine Oil Company by the Ruler of Qatar.

Includes a translation of a letter from Sheikh Ali Bin Abdulla Al Thani to the Political Resident in Bahrain, submitting proof of Qatar's claim (1-3).
