NEW DELHI, Nov. 30—Prime Minister Indira Gandhi called on the Pakistanis today to demonstrate their desire for peace by withdrawing their troops from East Pakistan, where Indian‐supported Bengali insurgents are battling the Pakistani Army.

“This would be a positive response—a gesture for peace,” the Indian leader told an appreciative, desk‐thumping up per house of Parliament.

The very presence of Pakistani troops in East Pakistan “is a threat to our security,” she said indicating that India would not relax her efforts to force the Pakistani troops out.

Reply to Suggestions

Mrs. Gandhi's call for a Pakistani evacuation was very clearly a negative answer to those countries, such as the United States and Britain, that have suggested that both India and Pakistan withdraw troops from the border to defuse the situation.

It was also, according to official sources, an assurance to the Pakistan Government that if it wanted to evacuate its troops from East Pakistan, India would see to it that they could leave without obstruction.

India's position is that Pakistan has posed the threat to Indian security, not vice versa, and that India will therefore not withdraw her troops until the threat is removed.

‘Cannot Allow Annihilation’

In her speech to the upper house—the Rajya Sabha—winding up a three‐hour debate about the recent tour she made of Western countries to explain India's predicament, Mrs. Gandhi declared: “We cannot allow the annihilation of the people next door to us. That is what has to be understood clearly.”

The speech was the clearest and firmest declaration the Prime Minister has made on India's determination to end the West Pakistani military presence in East Pakistan. Troops from the West, 1,000 miles away across Indian territory, have been trying since March to crush the Bengali autonomy movement, which has now declared the East in dependent as Bangla Desh, the Bengal Nation.

Mrs. Gandhi said that the next month would be a period of great difficulty. Her statement was Interpreted as an indication of the urgency she feels in seeking a solution to the crisis.

India seems determined not to let the situation freeze, but instead to keep increasing the military pressure on Pakistan. New Delhi apparently sees this as the only way to wring a settlement from Pakistan that would allow the millions of East Pakistani refugees who have fled to India—and threatened her stability—to return to home.

‘Part of Same Game’

Mrs. Gandhi referred to “Pakistan's persistent efforts to internationalize the issue,” and said that moves to bring the crisis before the United Nations Security Council were “part of the same game—that is, to confuse the realities of the situation.”

“Those who are moving in this direction,” she said, “cannot but be suspect in the eyes of the Indian people.”

There were reports from the United Nations on Friday that Japan, and Belgium and Italy jointly, were making efforts to get the Security Council to consider a resolution calling for a cease‐fire. The United States has said that a move in the Council is only one of several possibilities being considered.

Explaining why Indian troops would not be withdrawn from the Pakistani border, either in the West or the East, under the present circumstances, she referred to the two Indian‐Pakistani wars: “Having been taken unawares by Pakistan twice in the past, we cannot afford the risk—especially in the West, in Kashmir.”

“However,” she went on, “I would certainly welcome withdrawal of troops. And I think the troops that should be with drawn are the Pakistani troops in Bangla Desh.

“They are far from their homes. They are suffering. I think they should be taken back to their families and friends in West Pakistan,”

Mrs. Gandhi spoke for 25 minutes partly extemporaneously.

She said that in her view, the people of East Pakistan “will not settle for anything less than liberation.”

She praised the Mukti Bahini, or Liberation Forces, as the Bengali insurgents call themselves, and said they were “fighting very bravely.”

“They have our good wishes,” Mrs. Gandhi said, and then— after a pause—added: “And they have our support also”

The Prime Minister concluded her speech by saying: “Nobody can predict what the future will bring. There is no magic solution which will end the suffering of the refugees or the burdens we are facing. But I feel we and the people of Bangla Desh will emerge from what is a dark period for us, and that they will be able to make new life for themselves.
