UNITED NATIONS, N. Y., Dec. 11—Foreign Minister Zulfikar Ali Bhutto of Pakistan, who arrived here yesterday to press his Government's case at the United Nations, remained silent and inaccessible today as Pakistani officials disowned a proposal by a local commander in. East Pakistan for an immediate cease‐fire.

Some delegates speculated that the Government of President Agha Mohammad Yahya Khan may be divided on how to react to the deteriorating military situation in East Pakistan and that Mr. Bhutto may have been unable to get new instructions since his arrival.

Agha Shahi, the Pakistani Ambassador, conferred tonight with Secretary General Thant. A meeting between Mr. Thant and Mr. Bhutto had been scheduled for yesterday but was canceled.

Mr. Shahi said after the meeting that he had told Mr. Thant Pakistan was not asking for a new meeting of the Security Council. Many delegates had expected Mr. Bhutto to make such a request. “We stand on the resolution passed by the General Assembly—ceasefire and withdrawal,” Mr. Shahi said.

Letter Is ‘Disowned’

In answer to a question, Mr. Mehs said that his Government had “rescinded and disowned” a letter to Secretary General Thant from Maj. Gen. Ali Farman, military adviser and chief secretary to the Governor of East Pakistan, asking for an honorable cease‐fire and a political accommodation with the Bengali insurgents.

“Dacca will be defended,” Mr. Shahi said grimly.

He said that Mr. Bhutto had been indisposed but was feeling better and might see the Secretary General on Monday.

Mr. Bhutto held two long meetings yesterday and today with Chino Kuan‐hua, the chief Chinese delegate to the United Nations, and a short meeting yesterday with George Bush, the United States representative to the United Nations.

American officials refused to answer all questions about the nature of the meeting, which was held in Mr. Bhutto's suite at the Pierre Hotel. Mr. Bush had strongly supported Pakistan's case in the Security Council and in the General Assembly and had branded India an “aggressor.” Subsequent statements by officials in Washington have been more evenhanded. China is giving all‐out diplomatic support to Pakistan.

Foreign Minister Swaran Singh of India said after meeting with Mr. Thant that the government of Bangla Desh, or Bengal Nation, the name given given by the insurgents to East Pakistan, had to be part of any settlement and that Indian troops would not be withdrawn as long as President Yahya Khan's “declaration of war” was still in force.”

The turbanned Indian leader said: “Pakistan must accept the reality, which is that [East Pakistan] is now controlled by the peoples' representatives of Bangla Desh.”

Most members of the Council, like most United Nations countries, are reluctant to give any form of recognition to a secessionist movement.

Some delegates speculated that Mr. Bhutto had found upon his arrival here yesterday that events in East Pakistan had outstripped the instructions he had received before leaving Islamabad three days earlier. General Farman's letter to Mr. Thant, though rescinded, was an important factor in speculation here about internal dissension within the Pakistani Government and Army.

In his letter, General Farman said that he had been authorized by the President of Pakistan to call upon “the elected representatives in East Pakistan to arrange for the peaceful formation of a government in East Pakistan.”

“This is a definitive proposal for the peaceful transfer of power,” General Farman wrote, adding that “the question of surrender will not be considered” and that the bloodshed would continue if his proposal were not accepted.

The proposal specifically called for a cease‐fire, repatriation of civilian and military personnel from East to West Pakistan with full honors, safety for all persons settled in East Pakistan since 1947 and “guarantees of no reprisals.”

The letter, which was forwarded by Paul‐Marc Henry, the United Nations representative in Dacca, was distributed to some members of the Security Council by Mr. Thant's staff before President Yahya's counter order arrived.

India's Foreign Minister, Swaran Singh, arrived here from New Delhi early this morning accompanied by T. N. Kaul, the second‐ranking official in the Indian Foreign Ministry.

“The situation has become untenable for the Pakistani forces in the east,” one Indian diplomat said. “If they surrender, our forces will give them the full protection provided by international conventions; if they don't surrender, they will risk being slaughtered by Bengali irregulars.”

Justice Abu Sayeed Chowdhury, the leader of a Bangla Desh delegation here, issued a statement saying: “Bangla Desh will observe all the four Geneva conventions relating to the wounded, the sick, the prisoners of war, and treatment of civilian populations. We shall most strictly follow the human‐rights provisions of the United Nations Charter.”
