KARACHI, Pakistan, April 22 — India has given assurances that she does not recognize the so‐called Bangla Desh regime proclaimed by separatists in East Pakistan, the Pakistani radio said tonight.

The radio reported that the assurances were conveyed to the Foreign Ministry in Islamabad, the Pakistani capital, by B. K. Acharya, India's High Commissioner, or Ambassador, there.

According to the broadcast, Mr. Acharya also said that India would not “grant any diplomatic privileges” to M. Hossain Ali, the former Pakistani Deputy High Commissioner, or consul, in Calcutta, who last Sunday proclaimed himself the Calcutta representative of Bangla Desh — Bengali for Bengal Nation, the name the separatists have given to East Pakistan.

Information Awaited

The Pakistani radio said the Indian High Commissioner had declared that his Government would fulfill its obligation with regard to the vacating of the premises of the mission in Calcutta.

“The Pakistani Government,” the broadcast said, “is awaiting further information from its High Commission in New Delhi so that it can ascertain how sincere the Indian Government is” in its assurances.

The points made by the Indian representative in Islamabad appeared to remove two major areas of potential friction between the two countries. But they did not bear upon Pakistan's main charge against India—that the Indian Government is sending armed infiltrators into East Pakistan to foment trouble there. These charges have been denied by India.

Meanwhile, the Government news agency quoted martial law authorities in Dacca as having said that “reports of surrender” by soldiers who had been “misled by antistate elements” were now pouring in from all parts of East Pakistan.

The agency also said that East Pakistanis in the port city of Chittagong were turning in “miscreants” to the authorities.

These reports illustrated the Government”s contention that public opinion in East Pakistan was now against the antigovernment elements there.

The Government news agency has said that the East Pakistani populace has been antagonized by the behavior of the “miscreants.” It has distributed reports of wanton shelling, torture and other actions ascribed to the “antistate elements.”

Somewhat similar accounts of suffering at the hands of hostile elements have reportedly been brought back by West Pakistanis who have been returning here by ship in recent days.

The passenger ship Shams arrived yesterday from Chittagong. Her passengers were largely West Pakistanis—Pathans and others—who had preferred to leave East Pakistan.
