The United Nations Iraq–Kuwait Observation Mission (UNIKOM) was established on April 9, 1991 following the Gulf War by Security Council Resolution 689 (1991) and fully deployed by early May 1991. The task of the 300 military observers was to monitor the demilitarized zone (DMZ) along the Iraq-Kuwait border and the Khawr 'Abd Allah waterway, deter border violations and report any hostile action. On February 5, 1993, under Security Council Resolution 806, the mandate was extended to include physical action to prevent violations and the force was expanded to an intended three mechanized infantry battalions plus support.
