RAWALPINDI, Pakistan, Dec. 15—With the fall of Pakistani forces in East Pakistan seemingly only hours away, Pakistan's central Government here tonight demanded proper treatment by the victorious Indians of prisoners of war and of minority groups.

The Foreign Office note that made the demand reflected deep official fears that the Indian victory would lead to a bloodbath of reprisal killings by Bengali militants against Pakistani troops, their political and military collaborators and the non‐Bengali population.

There are about two million non‐Bengalis in East Pakistan out of a population of about 75 million. Since Pakistani Army repression of Bengali nationalism in the eastern wing began last March, the non-Bengalis have been the mainstay of local civilian support for the army.

A spokesman said tonight that the note had been issued because of an Indian announcement that a joint command had been formed for both the Indian Army and the Mukti Bahini (Liberation Forces) secessionist guerrillas fighting in East Pakistan. The Indian command is said to have threatened to turn over captives to the Bengali guerrillas for reprisals unless there is an immediate surrender of Pakistani forces.

Geneva Conventions Cited

The Pakistani note said that “some friendly governments,” presumably the United States especially, had made strong representations to India calling for strict application of the Geneva Conventions, especially with respect to prisoners, protection of all minority groups and cessation of bombing of civilians in cities.

There were indications from highly placed diplomatic and Government sources today that Pakistan's leadership has accepted the loss of East Pakistan. But such acceptance does not necessarily imply that Pakistan is willing to accept a cease‐fire.

First, Pakistan seems certain to insist on the safety of her 70,000 troops in East Pakistan. If India would permit a third nation, such as the United States, to evacuate these men and other West Pakistani officials there, a start toward Pakistani agreement to a ceasefire might be made.

A vital Pakistani condition to a cease‐fire is understood to be the guarantee that India would withdraw from any territory she has taken during the last two weeks either in East Pakistan or Kashmir.

If India insists on the forceful “rectification” of the ceasefire line established in Kashmir in 1965, Pakistan seems certain to fight to the end.

But there are fears here, supposedly based on high‐level intelligence reports from India, that the Indians intend to seize all of Kashmir and if necessary crush Pakistan as a nation.

Deep Gloom Here

The atmosphere here today was one of deep gloom both on the part of officials grieved at the loss of more than half the country and on the part of diplomats who foresee months of bloodshed and destruction ahead.

For a few Pakistanis there appeared to be hopes of brighter future.

“East Pakistan has for Some time been a stone around our neck obstructing economic development and preventing any real representative government from functioning,” a Pakistani official remarked. “If the Indians will now just leave us alone in the West we can build is greater country than ever before.”

But most of the people of West Pakistani up to now have regarded the conflict as a holy war in which death is better than defeat.

Meanwhile, the commander of Pakistan's Air Force said tonight that he believed India was using the SAM‐3 surface-to‐air missile, the most advanced Soviet anti‐aircraft missile.

Speaking with newsmen, Air Marshal A. Rahim Khan said he believed SAM missiles had been deployed at several Indian bases close to the Pakistani borders.

No Pakistani losses are known to have been caused by antiaircraft missiles, he said, although three Pakistani planes have been brought down in undetermined circumstances.

“We have no photographs of SAM‐3 sites but the army say they saw six missiles fired at our planes and our pilots have seen missile flames at night,” the commander said. “There must be Russian technicians at those bases.”

He said missile sites were believed to be in place near Amritsar and Pathankot near the West Pakistani border.
