The Balochistan region is split among three countries: Iran, Afghanistan and Pakistan. Administratively it comprises the Pakistani province of Balochistan, the Iranian province of Sistan and Baluchestan, and the southern areas of Afghanistan, which include Nimruz, Helmand and Kandahar provinces.[8][9] It borders the Pashtunistan region to the north, Sindh and Punjab to the east, and Persian regions to the west. Its southern coastline, including the Makran Coast, is washed by the Arabian Sea, in particular by its western part, the Gulf of Oman.
