Iran's secret revolutionary court executed 11 more top officials of the shah's government today, the national radio announced, after granting acquittals Tuesday for the first time in the two months since the new government took power.

The dead included two former chiefs of the SAVAK secret police, Gen. Hassan Pakravan, who was also an ambassador to France and Pakistan, and Gen. Nasser Moghadan, who also served as speaker of Iran's former llower house of the parliament.

Meanwhile, Tuesday the government acknowledged for the first time that unemployment has been responsible for the most recent unrest, even bringing some disgruntled workers to call for the return of Shah Mohammad Reza Pahlavi.

The government also was confronted with the strongest attack on it yet by one of Iran's new political parties, The National Democratic Front, a small liberal group led by lawyer and human rights activist Hedayatollah Matin-Daftari, warned Tuesday that further excesses by revolutionary committees "well result in a regime worse than the past one."

The Front's statement addes, "With the continuation of this situation the country will never see the face of freedom and independence."

Matin-Daftari has been the leading critic of the revolutionary committees' summary trials and executions of officials who served the shah-trials that a government spokesman said may go on for another year.

As if to counter the new government's worsening image, the state-run radio Tuesday publicized the acquittal Monday of 16 people on trial in revolutionary tribunals. The radio also announced that a former agent in Tehran of the secret police, SAVAK, was given a one-year prison term. All the previous trials of the shah's former agents had resulted in death sentences.

At the same time, however, the courts Tuesday went ahead with additional executions, sending at least three more former policement and SAVAK agents and a martial law administrator before firing squads today. Late-night executions put Monday's toll at 12, the highest one-day total since the trials began.

The government spokesman, Deputy Prime Minister Amir Entezam, said the trials may continue for "about a year, or God willing, a little less." He said the government approved of the executions and did not mind the revolutionary courts' failure to inform the Cabinet of the progress and results of the trials before the executions.

Government ministers learned of the execution of former prime minister Amir Abbas Hovyeda , for example, when it was announced on the radio.

Some ministers, however, are understood to be unhappy with the situation. The minister of Justice, Assadollah Mobasheri, has not appeared at his office for the past four days and is reliably reported to have submitted his resignation in protest over the revolutionary trials, which he wants put under his authority, Entezam sad reports of the resignation were "just rumors."

The spokesman acknowledged that jobless workers in the troubled Kurdish region of western Iran had marched to protest unemployment "and even shouted 'long live the shah' and demanding his return."

An independent witness described a similar march in the central city of Isafahan in which workers shouted "jobs bread, or bring back the shah."

Both marches were tiny in comparison with the huge demonstrations against the shah before the February revolution.

Tehran newspapers reported that more than 13,000 idle industrial workers in the sub-western oil town of Abadan had begun a sit-in to demand jobs.
