DACCA, Pakistan, Dec. 28 —The acting president of the Bengalis’ East Pakistan regime said today that his government would welcome the establishment of diplomatic relations with the United States, but that the United States must take the initiative.

The acting president, Syed Nazrul Islam, said, “We have been greatly disappointed in the United States,” but “We do not hold this against the American people.”

Speaking at his first joint news conference with the eight members of his cabinet, Mr. Islam refused to say whether he would demand that India hand over the former leaders of the Pakistani regime into the custody of Bangladesh, the nation proclaimed by the Bengali separatists.

Many Bengalis, angered by the massacre of thousands of their compatriots by the Pakistani Army, have been pressing the government to insist that India let them try the Pakistani officials for war crimes. The Indian Army holds more than 90,000 Pakistani troops and several thousand Pakistani civilians under its custody in East Pakistan.

First Prisoners Leave

The first group of Pakistani prisoners left Dacca today for internment in India. Some 2100 Pakistani troops in sand-colored uniforms boarded trucks in the Dacca military cantonment for the trip to India.

All of the 90,000 military prisoners are expected to be transferred to India within 10 days. But the fate of the civilian prisoners has apparently not yet been worked out between India and the Bengali government here.

Mr. Islam, dressed in a white lungi, the Bengali cotton skirt, and a black vest, renewed his appeals to the new Pakistani President, Zulfikar Ali Bhutto, to release Sheik Mujibur Rahman, the Bengali leader, who has been imprisoned in West Pakistan.

“Mr. Bhutto has no right to keep the father of our nation under his control,” Mr. Islam said.

In announcing that his administration would welcome recognition from the United States, Mr. Islam said: “We shall not forget the role played by the United States against us.”

But Mr. Islam added: “Though it is late, Mr. Nixon can still recognize that Bangladesh is real state. It's up to the United States to improve relations.”

Referring to the Biharis, a non‐Bengali minority group of two million people, Mr. Islam promised: “We guarantee full protection of the law for life and property to every person without discrimination.”

The acting president insisted that “law and order has been fully re‐established.”

However, two Biharis from the town of Mirpur who tried to get on a bus to go to a nearby market yesterday were found today by the road with their throats slit.

In another of the continuing sporadic incidents of violence, six Bengali youths armed with rifles entered the United States Information Service library in Dacca today in search of suspected collaborators. They left after learning that the men they were looking for had not reported for work during the last week.
