NEW DELHI, April 26—The Indian Government imposed restrictions today on the travel of Pakistani diplomats and their families and servants, making it impossible for them to leave India without New Delhi's permission.

The Government said it was doing this in retaliation for similar restrictions that Pakistan had allegedly imposed—but not announced—recently on the travel of Indian diplomats in Pakistan.

This latest move in the diplomatic war between India and Pakistan came as the civil war in East Pakistan—with the Pakistani Army trying to crush the Bengali independence movement—moved into its second Month. Clashes between the army and the independence forces were reported in several places.

The diplomatic infighting— an outgrowth of the civil war, which Pakistan has sought to attribute largely to the activities of “Indian infiltrators”— centers on India's attempt to bring home her diplomats from her Deputy High Commission, or consulate, in Dacca, East Pakistan, and on Pakistan's at tempts to remove the Bengali diplomats who took over Pakistan's Deputy High Commission in Calcutta April 17 in the name of Bangla Desh, the Bengal nation.

Ouster Asked by Pakistan

The current dispute began eight days ago when the predominantly Bengali staff seized the Calcutta mission. Pakistan demanded that India remove the “antistate elements” from the mission. India replied that while she had not accorded recognition to the Bangla Desh government, the dispute over the mission was a property dispute that the Pakistanis had to settle among themselves.

India, meanwhile, had been trying unsuccessfully to get permission from Pakistan to evacuate “some” diplomats and families from her Deputy High Commission in Dacca. India said it had become impossible for her Dacca personnel to “live and move about safely.”

Last Wednesday, the Pakistani Government announced that it was sending Mandi Masud from its High Commission in New Delhi, the equivalent of an embassy, to take over as Deputy High Commissioner in Calcutta.

India recognized Mr. Masud as the new Deputy High Commissioner, but on his arrival in Calcutta, though he had police protection, he was harassed and hounded by demonstrators— Indian Bengalis—and had to take refuge at the Calcutta air port's V.I.P. lounge.

Then, three days ago, charging India with failure to afford Mr Masud “necessary facilities,” Pakistan announced that she was closing her Calcutta mission and requested India to shut down her Dacca mission.

Both missions were officially closed today, although in Calcutta the action was only symbolic, since the Pakistani mission building remained in the hands of the Bangla Desh adherents.

Pakistan also asked India to send back the entire Pakistani staff of the Calcutta mission, including the dissident Bengalis. India has responded by saying that she will make arrangements for all those who want to go back to Pakistan, but that she cannot force any one to leave.

The Pakistani High Commission in New Delhi, in a note handed to the Indian Foreign Ministry today, said that the safe‐conduct and return of the Indian staff in Dacca “will be provided strictly on the principle of reciprocity.”

This afternoon, the Foreign Ministry here announced that all personnel of Pakistani missions in India would have to obtain “prior permission” from the Indian Government to leave the country. “The purpose of this new procedure,” it said in a note handed to the Pakistani High Commission, “is to insure reciprocity and the safety and security of concerned personnel.”

Incident Protested

This note, and another delivered yesterday without publicity, complained of restrictions imposed on Indian diplomats for travel within Pakistan, but they specifically pro tested the “highly objection able treatment” last week of Mrs. K. C. Sen Gupta, wife of the Deputy High Commissioner in Dacca.

According to the Indian notes, Mrs. Sen Gupta was subjected last Wednesday to a search of her person at the Dacca Airport while she was on her way to Karachi, and then was prevented from flying from Karachi to New Delhi by Pakistani officials whose behavior was described as “in suiting” and “outrageous.”

Two days later, the notes said, Mrs. Sen Gupta tried to leave Karachi again, this time with the regular Indian diplomatic courier, but they were told they could not go. It was only through the intervention of the Indian High Commissioner with the Pakistani Foreign Secretary that the diplomat's wife and the courier were eventually permitted to fly to New Delhi, the notes said.
