Town (pop., 1991: 83,770), northeastern Bosnia and Herzegovina.
Deposits of rock salt are located nearby; in the 10th century the town was called Soli (meaning "salts"), and its present name is from the Turkish tuz , "salt." It was a Turkish garrison town from 1510 until it passed to the Austro-Hungarian Empire in the 19th century. It was incorporated into Yugoslavia in 1918. It is the centre for a mining region and an agricultural district. It was a target during the war in Bosnia in the 1990s (see Bosnian conflict ).
