DACCA, East Pakistan, March 6 — The six‐day general strike that had been called by Sheik Mujib ended today, and the city returned to full activity, with shops and other businesses reopening and public transportation resuming.

During the last three days the strike was in effect only from 6 A.M. to 2 P.M.

The strike was marked by bloody clashes between troops and demonstrators and sporadic outbreaks of looting and property destruction.

Hundreds of East Pakistanis were killed or injured by troops during the last week, and resentment here has been further aroused by President Yahya's tough statement today that he was determined to keep martial law in force until the Assembly drafts a constitution acceptable to him.

Observers here feel that if Sheik Mujib seems to yield at all to the leaders in the West, the nationalist movement here may be taken over by more radical elements that want to proclaim full independence.

East Pakistanis have long complained that they have been dominated politically and exploited economically by the West.

An increasing number of foreign residents of Dacca are leaving as prospects for a peaceful settlement of the crisis seem to dwindle.

After President Yahya's speech, processions wound through the streets and tens of thousands of marchers shouted slogans such as “Independence” and “End Martial Law.”

In central Dacca, 250 convicts fought their way out of a prison. Seven of them were killed and six injured when the police fired in an attempt to stop the escape.

The prisoners went to one of the headquarters of the Awami League, expressing loyalty to Sheik Mujib and shouting slogans for the independence of East Pakistan.
