evidence: The Kuwaiti mainland, with no mountains, rivers or other natural features, was for a long time a transit area for nomadic tribes and caravans. Such freedom of movement made delineation of borders rather difficult. On July 7, 1965, a neutral zone was created between the State of Kuwait and the Kingdom of Saudi Arabia. The northern part of the partitioned zone is administered by Kuwait, whilst the southern part is the administrative responsibility of Saudi Arabia. The crude oil extracted from the partitioned zone is equally shared by both countries. [...] There are nine islands off the coast of Kuwait: Failaka, Bubiyan, Miskan, Warba, Auhha, Umm Al-Maradim, Umm Al-Naml, Kubbar and Qaruh. Bubiyan, the largest island of the State, has an area of 863 sq km and is connected with the mainland by a concrete bridge. Warba, at the north extremity of the Gulf, occupies an area of 37 sq km. Miskan and Auhha lie on the north and the south of Failaka island, respectively. Located at the mouth of Kuwait Bay, a lot of Islamic antiquities have been found on Umm Al-Naml island. Kubbar and Qaruh lie at the southern end of the Gulf and have been the favourite homes for large flocks of sea birds.
