CALCUTTA, India, Aug. 15—The new Government of Bangladesh moved swiftly today to consolidate its control following the pre‐dawn military coup d'etat in which Sheik Mujibur Rahman was overthrown and apparently killed.

The country's frontiers and the airport at Dacca, the capital, 150 miles northeast of here, were closed, and most normal lines of communications with the rest of the world were cut off. Martial law and a 24‐hour curfew were imposed indefinitely.

But the official Bangladesh Radio, monitored here, kept up a steady stream of bulletins painting a picture of a quick return to normality under the new President, Khondakar Mushtaque Ahmed, the former Commerce Minister.

Some Deaths Reported

Diplomatic sources also said that the country was calm. But there were unconfirmed reports from border towns near here that a number of people resisting the coup had been killed.

Mr. Mushtaque Ahmed took the oath of office this afternoon in a ceremony attended by the heads of the country's three defense services. Each made a statement supporting him. He then appointed a new 10‐man civilian Cabinet that he said would replace the “autocratic government” of Sheik Mujib. Most members of the “new revolutionary government,” though, were in the Previous government.

All patriotic and peace‐loving citizens have been requested to cooperate with the Government,” the radio declared. “Anybody trying to resist will be dealt with severely.”

‘Coterie Rule’ Charged

In a broadcast tonight, President Mushtaque Ahmed accused the, old government of “rampant favoritism and corruption” that he said resulted in the accumulation of wealth in the hands of the few while the masses of Bangladesh suffered.

He said that the country's main industry, jute, had come to the point of ruin because of “coterie rule,” and that the people had demanded a change.

Now, he continued, the country will be free of its malaise, and a sense of values and justice will be restored.

Turning to foreign policy, the new President said he looked to friendly relations With all countries, including those “who have not yet been our friends.”

“Our policy will be friendship with all, and malice toward none,” he said. He added that the country would continue to support “our Arab brothers” in the territorial struggle with Israel.

Sheik Mujib, the 55‐year‐old hero of the Bengal National Movement that finally brought Bangladesh independence from the rest of Pakistan three and one‐half years ago, was apparently one of the few casualties of the coup.

The radio said that he had been killed “during the takeover” this morning, but it did not say how. Other sources reported from Dacca that gunfire had been heard before dawn near his residence.

According to another report, Prime Minister Mansoor Ali, whose role in the government was largely ceremonial, was also killed, along with two of Sheik Mujib's nephews.

Mr. Ahmed, who was an associate of Sheik Mujib for 25 years in the often‐violent Bengali struggle, spending years in the same jails, said he had decided to take over the impoverished and overcrowded nation today in the “greater interest of the country and view of the historic necessity.”

The new President, a 56‐yearold lawyer who is regarded in Bangladesh as a conservative, called upon the people to back him with determination and discipline, to turn the country into a peaceful and prosperous land.

Another Government spokesman broadcast an assurance of the safety and well‐being of all foreigners in Bangladesh, adding:

“The new Government appeals to all peace‐loving and friendly countries of the world to accord recognition.”

The Indian Government, which was a firm ally of Sheik Mujib, ‘had no immediate comment on the coup. There was no indication of any troop movements.

This morning it announced that the curfew would be lifted for an hour and a half around noon so that people could go to their regular Friday prayers. Later it reported “unprecedented crowds” at ??? mosques.

Sheik Mujib, who referred to himself as “the father of the nation,” had been a very popular leader. But in recent years he had been widely criticized for his inability to cope with Bangladesh's overwhelming problems, which center on poverty and population.

One of the most densely populated countries in the world, Bangladesh is only the size of Wisconsin, with 75 million people and few resources, Much of its area is flooded every year. With 10.000 babies born there every day, the country's plight has been regarded as hopeless by many foreign exports.

Since coming to power after the 1971 Pakistan‐Indian War, which insured the independence of Bangladesh, Sheik Mujib adopted an increasingly authoritarian position. He arrested a number of his political opponents and in January he had the Constitution rewritten to give himself more power.

Sheik Mujib's associates and his government acquired more and more of a reputation for ineptness and corruption.

Several of his allies in the government were apparently removed from office in the coup, but Radio Dacca left unclear what had happened to them.

For example, it said that President Mushtaque Ahmed had been sworn in by “acting chief justice Mohammed Hossain,” but made no reference to A. M. Sayem, a close associate and appointee of Sheik Mujib who had been the chief justice.

Similarly, the radio said that the new government had received the support of Abdul Hasan Khan, who it identified as the acting director general of the powerful, paramilitary force upon which Sheik Mujib had depended, to the exclusion of the regular armed forces. But it offered no explanation about what had happened to Brig. Nuruz Zaman, who had headed the paramilitary force.

President Mushtaque Ahmed, a graduate of Dacca University, entered politics as a young follower of Mohandas K. Gandhi's “Quit India” movement of 1942, the beginning of the concerted drive that ultimately forced Britain to relinquish the subcontinent — an area now made up of India, Pakistan and Bangladesh.

After Indian and Pakistani independence in 1947, the target of the Bengalis’ struggle became the government in West Pakistan. The Bengalis, living in what was then East Pakistan, regarded the central Government as repressive. The vehicle of the fight was the Awami League, of which Sheik Mujib was the leader. Mr. Mushtaque Ahmed was a theoretician and prominent member.

When Bangladesh declared her independence from the rest of Pakistan in March of 1971, Mr. Mushtaque Ahmed was foreign minister of the provisional government. After independence, when the Awami League became the governing political party, he became its senior vice president.
