UNITED NATIONS, N. Y., Dec. 21—The Security Council, meeting in a night session, called today for the withdrawal of Indian and Pakistani forces “as soon as practicable” to their respective territories and demanded that the cease‐fire re main in effect until then.

The vote in the 15‐member Council was 13 in favor, none against. The Soviet Union and Poland abstained. The resolution had the explicit endorsement of the Governments of India and Pakistan.

Pakistan was reported to have desired a formal United Nations endorsement of the existing cease‐fire, particularly in Kashmir. This, according to a Western diplomat, was the immediate purpose of the Council's action,

Agha Shahi, the delegate of Pakistan, addressed the Council after its vote and chastised its members for having failed to act earlier. He declared that East Pakistan remained the territory of Pakistan.

India's Foreign Minister, Swaran Singh, called attention) to “the existence of Bangladesh” and said that Indian forces there would withdraw as soon as practicable. He added that their presence was needed for the time being “for the protection of Pakistani troops who have surrendered and for the prevention of reprisals.”

The Council's action was its first since the beginning of the conflict between India and Pakistan. The Council had been unable to reach agreement in eight meetings as the Soviet Union vetoed three resolutions that would have called for a cease‐fire and withdrawal while the fighting was still going on.

The key paragraph of the resolution said that the Council “demands that a durable cease fire and cessation of all hostilities in all areas of conflict be strictly observed and remain in effect until withdrawals take place, as soon as practicable, of all armed Tomes to their respective territories and to positions which fully respect the cease‐fire line in Jammu and Kashmir,”

The Council had been ready to vote on the resolution yesterday but postponed its meeting until Agha Shahi, the Pakistani delegate, received a specific endorsement of the text from Zulfikar Ali Bhutto, the new President of Pakistan.

The agreement was hammered out in long consultations with the Indian and Pakistani delegations by Abdulrahim A. Farah, the delegate of Somalia, These consultations, with Mr. Farah acting as the mediator, started Friday night.

Mr. Farah tonight read into the record of the Council an explanatory statement which was understood to form part of the agreement between. India and Pakistan.

It said that in the eastern theater, meaning Bangladesh in Indian terms and East Pakistan in Pakistani terms, there should be “complete withdrawal as soon as practicable and that in the west there should be “a process of disengagement leading without delay to withdrawal” of the troops of both sides.

Mr. Farah's statement also took note of the declaration by the Indian Government that it had no territorial ambition.

Mr. Farah's explanatory statement was necessary to bridge the gap between India's formal recognition of the state of Bangladesh and the Pakistani Government's continued insistence that its national territory continues to include East Pakistan.

The door to agreement on today's resolution was opened late last week, after the fall of Dacca, when a growing number of delegations became convinced the presence of Indian troops in East Pakistan would be necessary for some time to prevent the massacre of civilians and that the Council there fore should not call for immediate withdrawal.
