Karachi, March 3

President Yahya Khan of Pakistan in a last-minute attempt today to resolve the country's constitutional crisis, called a round table conference in Dacca on March 10. of the leaders of 12 parliamentary groups to iron out the main differences between the eastern and western provinces.

The President said he believed that the Constituent Assembly could be called within weeks if the leaders came to some understanding.

It remains to be seen whether Shaikh Mujibur Rahman, the Bengali leader will attend in view of his belief that the constitution can only be hammered out in a Constituent Assembly in which East Pakistan has a majority.

While East Pakistan has reacted violently against the postponement by President Yahya Khan of the first sitting of the Constituent Assembly, which was scheduled to take place in Dacca today, the more affluent western province, which would risk to lose its monopoly of power if the constitution was framed, has welcomed the decision.

As violence, arson, looting and a total strike paralysed East Pakistan for the second day today, Shaikh Mujibur called on his fellow East Pakistanis to confront the central Government in all spheres of life.

In a strongly worded attack on the central Government and on Mr. Z. A. Bhutto, the leader of the People's Party in West Pakistan, Shaikh Mujibur also announced that the general strike would continue until Saturday. He hinted that he would then announce his future plans.

Curfew was reimposed in Dacca today after a night of violence, arson and looting, Thousands of Bengalis defied the curfew order last night. Reports front the provincial capital indicate that two students were killed during a clash with the police.

Shops and business concerns remained closed in East Pakistan and apart from heavily armed military vehicles no other traffic appeared on the roads. The eastern province was cut off as all Government servants including those from post and telegraph offices joined the general strike.

Shaikh Mujibur. who led a huge rally through the streets of Dacca today. warned the western province that Bengal was on fire and if the conflagration continued the West Pakistanis would not be able to escape the flames.

In a direct attack on Mr. Bhutto, the Shaikh said that his own party and a few representatives from the western province had began to arrive in Dacca to attend the Constituent Assembly but "an unwarranted intervention prevented this sitting from taking place ".

In a reference to Mr. Bhutto's decision to call a strike in West Pakistan unless the meeting of the. Constituent Assembly was postponed, Shaikh Mujibur said that the President had taken the decision under pressure of a minority group Mr. Bhutto, whose decision to boycott the Constituent Assembly precipitated the present crisis, has apparently reviewed his rigid stand and hinted that he would be willing to meet Shaikh Mujibur to initiate a diagolue.

Addressing a hurriedly called press conference last night Mr. Bhutto said he had demanded the postponement of the National Assembly so that Shaikh Mujibur and western leaders could iron out their differences before the Assembly met.
