DACCA, Pakistan, Dec. 25 (Reuters) — West Pakistani soldiers who surrendered to India at the end of the 12‐day war in East Pakistan will be repatriated in a large‐scale operation starting tomorrow or Monday, informed military sources said today.

Some 30,000 Pakistani soldiers are being held in Dacca military camp under relaxed, almost casual, detention conditions.

Although the Pakistanis interviewed have spoken of their good treatment, they appeared anxious to return home to West Pakistan.

Senior military sources said Pakistani troops who surrendered to the Indian forces Dec. 16 would be moved out by all available land and water transport. They will first go to India, the sources said.

Meanwhile, there was doubt about the whereabouts of Abdu Mutaleb Malik, the former Governor of East Pakistan, who was reported to have been arrested on charges of genocide.

Mr. Malik and his Cabinet resigned on Dec. 15, a day before the Pakistani forces in the east surrendered to the Indian Army.

The officials were moved by the Indians to the military camp near Dacca airport.

But the Press Trust of India news agency still reported from Dacca today that Mr. Malik had been arrested and would be tried for the murder of thousands of Bengalis. A police bulletin last night listed Mr. Malik and eight of his former Cabinet colleagues as being among 48 by the police, the agency reported.

Reporters visited the camp today and talked with a number of former senior East Pakistani Government officials.

The Pakistanis were playing bridge on the porch of their bungalow. There was no sign of Mr. Malik, but he was reported to be in another part of the camp.

Puzzled by Reports

A senior Indian officer at the camp said he and other officers were puzzled by reports that Mr. Malik and the other officials had been arrested by officials of Bangladesh, the independent country proclaimed by the Bengalis in East Pakistan.

The return to normal in Dacca is moving at impressive speed. All Government offices have now reopened and most shops and private businesses in the city are operating.

Transport is one of the major problems. Few taxis are operating because of gasoline rationing.

River steamer service from Dacca to Chandpur, Barisal and Khulna has resumed; buses are operating from Dacca to Tangail and Aricha and the route to Comilla is expected to resume within a few days.

The Bangladesh government, headed by an acting President, Syed Nazrul Islam, has been engaged in daylong meetings at Government House since its arrival from Calcutta Wednesday.

All police stations and outposts in Dacca are said to be functioning.

Meanwhile, new evidence has come to light on the identity of those responsible for the massacre of Bengali intellectuals two days before the surrender. Right‐wing Bengali religious fanatics who supported Pakistani rule are now accused of the mass murder, at Mohammedpur, on the outskirts of Dacca.

Non‐Bengali razakar irregulars, who also backed the Pakistanis, were originally blamed for the killing of about 150 of Dacca's leading doctors, lawyers, professors, teachers and journalists.

But student groups and local newspapers have now laid the blame on the Al‐Badar—the extremist action front of the rightwing Moslem political party, Jamaat‐i‐Islami.

But students and other intellectuals also charge that a group of senior officers in the Pakistan Army had direct knowledge of the plans and that they supplied the weapons and otherwise encouraged Al‐Badar to kill those who opposed an Islamic state.

Survivor is Quoted

They say they have evidence, including an eyewitness account from one man who escaped, that all the executioners were Bengalis.

The aim, it is alleged, was to liquidate all nonreligious intellectuals. “Had the surrender not taken place Dec. 16, you would have found Dacca without a politically conscious Elite,” said Enayeteullah Khan, editor of the weekly newspaper Holiday.

This was not done in the fight against secessionists, they were just killing people for advocating secular ideals,” he said.

Spokesman for the Bangladesh Students League, which is affiliated with the guerrilla forces, said that the students and other military and civilian groups were now hunting down Al‐Badar members.

They said that more than 40 had been arrested and that other names were known.

Many bodies have been recovered from the marshlands around the Mohammedpur Brick Factory, where the killings were carried out.

The only man known to have survived the massacre, Delwar Hossain, 25, chief accountant with a Dacca company, has given a long account of the torture and killings in Bengali newspapers.

Mr. Hossein said he was taken from his house by Al-Badar guerrillas on the morning of Dec. 14, stripped to the waist, blindfolded and put aboard a bus.

Mr. Hossain said that when they arrived at the brickworks he saw about 140 people there. They had been lined up along the edge of a ditch and the shooting started.

He said he made a run for it in the dark after many people had been shot.

He said he swam to the other side of the river and took shelter with guerrillas there.
