It is a fairly well kept secret that Israel has been occupying parts of Saudi Arabia since 1967. Tiran and Sanafir are two islands with a combined area of 113 square kilometres, so they are small, and are in a very strategic location at the mouth of the Gulf of Aqaba, through which sea traffic to Israel's southern port of Eilat must pass en route to and from the Red Sea. Israel maintains an early warning post on the islands.
Although the Saudi Arabian government might claim that the islands are small, unimportant coral reef islands, their position is such that whoever controls them controls the Gulf of Aqaba. They are as important as the Hanish archipelago at the other end of the Red Sea over which a conflict raged in 1995. International arbitration determined that Hanish belongs to Yemen. The Israeli occupation of Tiran and Sanafir determines that, if nothing else, the Israelis control the islands and don't really care who they belong to. Saudi Arabia has fought for similar islands but seems to be reluctant to challenge the Israeli occupation. Is it because the islands have no material value?
But Saudi Govt. is so eager to meddle in Iran and UAE quarrel over 3 PG Island.
Emirate claims that iran has occupied the island but Iranian authorities and people hesitate that a country having a 100 history has had possessed island which belong to a 7000 years old country.
