DACCA, Pakistan, Aug. 14— This East Pakistani capital increasingly torn by violence and terrorism, looked today more like a city under curfew than one celebrating National Independence Day.

Army jeeps with heavy ma chine guns at the ready moved through rain‐swept streets that were decorated with green and white Pakistani flags but were largely deserted apart from wandering cows and sheep.

Residents told of mass migration from the city during the last few days apparently in anticipation of bloodshed today or tomorrow. In fact, Dacca looked emptier than it has in months.

During the last two weeks posters and leaflets have been distributed here by guerrillas of the Mukti Bahini, the Bengali separatist force, warning citizens to leave the city. The leaflets have predicted major attacks against Government installations and collaborators.

Bombing, shooting and sabotage occur every night but the most spectacular incident to date was the bombing Wednesday night of the Intercontinental Hotel in Dacca. Radio Bangla Desh, the clandestine guerrilla station, today formally acknowledged responsibility for the bombing.

3 Floors Damaged

The lower three floors of the hotel were heavily damaged by the blast and about a score of people, one of them American, were injured. The American, Clarence Callaghan, is an engineer from Augusta, Me. He is in serious condition at hospital here after heavily suffered leg and face wounds.

National Day, the observance of Pakistan's 24th anniversary of independence from Britain, has special significance here both from the national Government and the Bengali separatists opposing it.

President Agha Mohammad Yahya Khan has reiterated his insistence that East Bengal is part of Pakistan and will re main that way. From the Government's standpoint it is important to demonstrate national unity with a widespread show of flags, patriotic slogans and public enthusiasm for the martial‐law authorities from West Pakistan.

Seek to Mar Festivities

The guerrillas, whose allegiance is to Bangla Desh and not to Pakistan, were deter mined to spoil the holiday activities either by direct terror or by inducing the population to leave the city in a show of noncooperation.

In downtown Dacca, portraits of Mao Tse‐tung appeared with those of a Pakistani military leaders. Communist China is currrently considered here as Pakistan's only strong ally.

Street intersections in downtown Dacca were hung with huge cloth signs naming them after various West Pakistani and leaders, including President Yahya and the Governor of East Pakistan, Lieut. Gen. Tikka Khan.

Some posters depicted the burning of Indian flags. Along their long mutual borders in East Pakistan, Pakistani and Indian forces shell each other daily.

Americans and other foreigners here have been warned to stay off streets and to avoid crowds, and some have been leaving East Pakistan since the hotel bombing. The Bangla Desh radio has specifically denounced what it termed American support for the Pakistani Government.

The Intercontinental Hotel it self, despite heavy damage, remained open. Recorded music diverted the attention of dining room patrons from the sound of sledgehammer and shovels as workers continued to clear away the rubble of smashed walls and floors.
