UNITED NATIONS, N.Y., Dec. 11 — As the fighting has increased in Kashmir between India and Pakistan, a little known band of 45 United Nations observers has been sending daily reports to New York.

Yesterday, the observers' commander, Lieut. Gen. Luis Tassara Gonzales of Chile, informed the United Nations that his staff could not move about the area because of combat conditions.

“Since hostilities commenced on a large scale,” the general said, his band has had to limit observations to what could be seen from its own posts, “severely restricting contact between military observers and the respective military authorities.”

The Kashmir observer force, known as the United Nations Military Observer Group in India and Pakistan, and consisting of officers from various countries, has been reporting on conditions along the truce line of the disputed Kashmiri territory since January, 1949. It was one of the first peace‐keeping groups formed by the United Nations.

A major question today is whether India and Pakistan would allow a United Nations force between them in case of a cease‐fire.

There have been more than 20 United Nations peace missions since the formation of the world body, ranging from a force of more than 20,000 in the Congo in 1961 to such one‐man efforts as that of Dr. Gunnar V. Jarring, the Secretary‐General's representative in the Middle East. Several forces are still In being. The largest is the United Nations Force in Cyprus, now 3.000 strong, which has been on duty since March, 1964. Its mandate, for another six months, must be renewed before Dec. 15.

A similar force was the United States Emergency Force that separated Arab and Israeli forces along the Suez Canal from 1958 to 1967. It was armed for local self‐defense, but was forced to abandon the area when the Egyptian Army, decided to move forward.

The Korean War was by far the biggest operation involving the United Nations flag, but it is considered on a unique footing because, though the war was sanctioned by the Security Council, military operations in Korea were governed almost entirely by the United States.

The main obstacle to agreement on forming a United Nations standing force, as envisaged by the United Nations Charter, is that the Soviet Union says such a force must be directed by the Security Council and the military representatives of the five permanent Council members — the United States, Britain, China, France and the Soviet Union.

That would give Moscow a direct hand in the operation and a power of veto.

The Security Council was able to undertake the war against Communist North Korea without a veto because the Soviet representatives, at the time, were boycotting the Council to protest the presence of Nationalist China as a member.
