UNITED NATIONS, N. Y., Sept. 27—India's Foreign Minister, Swaran Singh, over the shouted objections of the Pakistani delegate, told the United Nations General Assembly to day that the Pakistani Government had unleashed a “reign of terror” and was conducting “deadly activities” in East Pakistan.

Mr. Swaran Singh said that recent Pakistani Government concessions to the East Pakistanis were “no more than eye wash.” He said that the “so called” civilian government that had been set up consisted of “figureheads” and that Sheik Mujibur Rahman, leader of the outlawed Awami League, and other elected representatives were being tried as traitors in spite of a proclaimed amnesty.

Mr. Swaran Singh spoke on the first day of the general de bate, which, at the outset of each Assembly is devoted to broad policy statements by most member governments.

Pakistani Objects

Agha Shahi, the representative of Pakistan, was on his feet objecting moments after Mr. Swaran Singh turned to the situation in East Pakistan. Mr. Shahi requested Adam Malik, the Assembly President, to rule Mr. Swaran Singh out of order on the ground that he was discussing the internal affairs of Pakistan. Mr. Malik did not intervene.

Mr. Swaran Singh Charged the Pakistani Government's actions in East Pakistan had violated the United Nations Charter and that it would be mockery of international justice to suggest that this was an internal issue.

Mr. Swaran Singh refrained from suggesting that the situation in East Pakistan should be discussed formally by the Assembly. There has been no attempt to enter an item about it on the agenda.

Right of Reply Used

Mahmud Ali, who is leading the Pakistani delegation during the Assembly, used the right of reply before the debate was closed for the day. He accused India of instigating and abet ting the East Pakistanis in their revolt against the West in a “well‐planned military effort”, to break up Pakistan.

The Assembly's general de bate has seldom opened on note of such hostility. Normally the sharply controversial parts of the speeches have been sub merged in diplomatic generalities.

As always, the general de bate was opened by Brazil— this time by Foreign Minister Mario Gibson Barbosa. Brazil requested and obtained this privilege at the first Assembly session on the ground that middle‐sized power—not a big power and not a small country —should open the debate on note of harmony.

All delegates were watching the policy declarations care fully for hints of any change in the line‐up on China.

Mr. Gibson Barbosa, like most of the other speakers, mentioned the question of the admission of Peking as being one of the topics of overriding importance before the Assembly.

Brazil has in the past voted with the United States in op posing Peking's entry. Mr. Gibson Barbosa gave no hint how Brazil would vote this time, but chided the United States.

Peking, he said, is not a newly discovered star in the constellation of great powers but has been “shining” a long time. What is new, he said, is “that one superpower has decided that the time has come to acknowledge the existence of another great power.”

Takes Arrival for Granted

Mr. Gibson Barbosa added that the arrival of the “new partner” was taken for granted, “whether it was today or to morrow.”

The new Iranian Foreign Minister, Abbas Sli Khalatbari, told the Assembly that his country recognized Peking as “the sole government of China,” which should take its “rightful place at the United Nations.”

Last year Iran abstained on the Albanian resolution calling for the admission of Communist China and the expulsion the Chinese Nationalist Government on Taiwan, but it supported the American resolution calling the China issue an “important question” requiring a two–thirds majority for approval.

Jean Keutcha, Foreign Minister of Cameroon, another country whose vote is regarded as doubtful, declared himself in favor of the restoration of “the legitimate rights” of mainland China — a choice of words that is close to the Albanian resolution.

Cameroon established relations with Peking in April. She abstained in the China vote last year.
