DACCA, Bangladesh, Aug. 201 (AP)—The new President of Bangladesh has assumed the power to set up special tribunals for punishing offenders.

President Khondakar Mushtaque Ahmed's proclamation assuming such power and defining the martial‐law administration was issued as communications with the outside world opened for the first time since a military coup overthrew the government of Sheik Mujibur Rahman and installed Mr. Mushtaque Ahmed. Sheik Mujib was killed in the uprising.

Foreign newsmen arrived at Dacca airport today after Bangkok and Calcutta air services were resumed.

Dacca appeared calm, with traffic flowing normally. Some troops were visible at the airport and at Government buildings and cruising the capital's streets in heavy trucks. Guards manned automatic weapons set on the truck cabs.

The President's proclamation stated: “Martial‐law regulations and orders made by me shall have effect notwithstanding anything contained in the Constitution of the People's Republic of Bangladesh.”

Constitution Is Kept

However, Mr. Mushtaque Ahmed said that the Constitution, “subject to this proclamation and martial‐law regulations,” would continue in force. Bangladesh radio said that, under the proclamation, martial law would, remain in force “until further Orders.”

According to the national radio, Mr. Mushtaque Ahmed said in his proclamation that he had taken over “all and, full powers” of the Bangladesh Government from the morning of Aug. 15 and placed the whole country under martial law.

The proclamation also said that the President could make new martial law regulations and establish special courts and tribunals to deal with offenses and decide on the punishment.

The radio said that all orders and proclamations issued under the martial law administration would be beyond the jurisdiction of any courts.

The radio said that 14 countries had so far recognized the new government. These included Nepal, Malaysia, Australia and Qatar, all of which announced recognition in the last 24 hours.

The radio added that the heads of the diplomatic missions of the United States, the Soviet Union and India called on the new President during the day.

The broadcast also said that the President had conveyed his “profound regrets” to Prime Minister Indira Gandhi over Sheik Mujib's death.

In her only public comment on the coup, Mrs. Gandhi said she was “deeply shocked” by the killing of Sheik Mujib.

“The people of India held him in deep respect and affection as a friend of this country and champion of the cause of goodwill and cooperation in the subcontinent,” she said in a condolence message on Monday.
