were no Indian troops in that territory. The 830 kilometre long ceasefire line established in the agreement started from a southernmost point just west of the Chenab river in Jammu. It ran in a rough arc northwards and then northeastwards to the map coordinate NJ9842, about 19 km north of the Shyok river. From the map point NJ9842, it was said to run due north to the international boundary with China, at a distance of about 60–65 km. Since there were no troops in that area of inaccessible glacial terrain, no effort was made to extend the ceasefire line between NJ9842 and the China border. This area, of the Siachen Glacier, eventually became a bone of contention between India and Pakistan. Another anomaly arose at the southern end of the ceasefire line in Jammu. From the terminus of the ceasefire line to the international boundary between Indian and Pakistani Punjab, there was a gap of over 200 km, which was covered by a recognised "provincial boundary" between Pakistani Punjab and the princely state of Jammu and Kashmir. India generally referred to this boundary as the "international border", whereas Pakistan referred to it as the "border" or the "working border". Map of the Agreement U.N. document number S/1430/Add.2 (which is the second addendum to the 1949 Karachi Agreement) shows the Cease Fire Line (CFL) marked on the Map of the State of Jammu and Kashmir. Title of this addendum reads: Map of the State of Jammu and Kashmir showing the Cease Fire Line as Agreed Upon in the Karachi Agreement, Ratified by the Governments of India and Pakistan on 29 and 30 July Respectively. (See Annex 26 to the third Interim Report of the United Nation Commission for India and Pakistan) U.N. Map illustrating Cease Fire Line as per Karachi Agreement 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. UNMOGIP's functions were to observe and report, investigate complaints of cease-fire violations and submit its findings to each party and to the
