Sanafir Island is an island in the Straits of Tiran east of Tiran Island. It is administered by Egypt. It measures 33km² in area. On 9 April 2016, the Egyptian government declared that Sanafir and Tiran Island fall within the territorial waters of Saudi Arabia, as codified in the maritime border agreement signed with the government of Saudi Arabia on the previous day. However, the agreement must be ratified by Egypt's Parliament, and has reportedly been quashed by an Egyptian judge. The deal moves forward the idea of building the Saudi–Egypt Causeway. The deal has caused turmoil in Egyptian politics erupting mass protests that accused President Sisi of "selling" Egyptian land. An Egyptian court gave its final ruling in January 2017, rejecting the deal and affirming Egyptian sovereignty on both the islands.
