evidence: Saudi Arabia and Qatar's ruler agreed in 1965 to delimit their boundary from Duhat as-Salwa in the west to Khwar Udaid on the Gulf in the east. (Qatar was then a British protectorate and Britain did not recognize the agreements, preferring to uphold Abu Dhabi's claim.) However, a 1992 clash between Saudi Arabia and Qatar claimed three lives; Qatar accused Saudi Arabia of attacking a border post at Khafus, while the Saudis stated that the clash took place inside Saudi territory between Bedouins from the two countries. In 1996, Saudi Arabia and Qatar signed a border demarcation agreement, and the two states completed the process in June 1999, signing demarcation maps of their common borders. Maritime Boundaries in the Northern GulfIn January 2000, Iran began drilling in the Dorra gas field in the Persian Gulf in an area claimed by both Kuwait and Saudi Arabia, only to stop three months later in response to their protests. Kuwait and Saudi Arabia concluded an agreement in July 2000 demarcating their maritime border. The accord gives Kuwait sovereignty over the islands of Umm al-Maradim and Quruh with a one-mile radius around each. Submarine gas reserves, estimated at 370 billion cubic meters, will continue to be shared between the two nations. For its part, Iraq protested the SaudiKuwaiti agreement, announcing that it will not recognize any deal that does not take into account the territorial rights of Iraq.
