The Karachi Agreement between India and Pakistan established a cease-fire line to be supervised by the military observers. These observers, under the command of the Military Advisor, formed the nucleus of the United Nations Military Observer Group in India and Pakistan (UNMOGIP). On 30 March 1951, following the termination of the United Nations Commission for India and Pakistan (UNCIP), the Security Council, by Resolution 91 (1951) decided that UNMOGIP should continue to supervise the cease-fire line in Kashmir.
