Representatives of Iran's ruling Revolutionary Council were rebuffed today in their effort to halt factional fighting between supporters of rival ayatollahs.

In the holy city of Qom, Aytollah Kazem Shariatmadari, the spiritual leader of this region's Turkish-speaking Azerbaijanis, forbade negotiations with the team and issued a statement supporting his partisans here and accusing the central government of reneging on an agreement reached with him last week.

His rival, revolutionary leader Ayatollah Ruhollah Khomeini, mean-while put out his statement blaming the troubles in Tabriz on "American spies" and calling on American voters not to reelect President Carter, whom he branded a "traitor."

The Revolutionary Council peace mission, headed by Finance Minister and former foreign minister Abol Hassan Bani-Sadr, was only able to see a Khomeini representative, Ayatollah Mohammed Enghji. Members of Shariatmadari's Moslem People's Republican Party declined to meet with the delegation.

Although the city remained tense tonight, there was no repetition of Sunday night's fighting between supporters of Khomeini and Shariatmadari, who is regarded as the country's second most popular ayatollah and the most revered religious figure here in his native Azerbaijan.

At least seven and perhaps as many as 11 persons were killed Sunday night when armed Khomeini supporters assaulted the radio and television station here, which had been held by Shariatmadari's forces since Thursday night. Reports of the injured ranged from 20 to 45.

Tonight the television station appeared to be under the control of the Iranian Army, but it remained unclear which of the two factions the Army supports. Workers at the headquarters of Shariatmadari's Moslem People's Republican Party said they no longer controlled the broadcasting station.

It also was unclear which side had control of the office of the governor general. It was said to have changed hands at least three times today, with Shariatmadari supporters, Khomeini followers and Army troops variously reported in control.

Demonstrations in Tabriz started Thursday, a day after supporters of Khomeini marched on Shariatmadari's house in the holy city of Qom to protest his opposition to parts of the new constitution that give sweeping powers to Khomeini. One of Shariatmadari's guards and another Iranian were shot to death in a melee in front of his house.

The demonstrators in Tabriz also demanded greater autonomy for the provinces of East and West Azerbaijan, whose residents form the largest of all the national minorities in Iran and make up one-third of the population.

Officials of the Moslem People's Republican Party which favors greater autonomy for residents here, refused to meet with the Revolutionary Council peace mission on Shariatmadari's orders. Shariatmadari, who is in Qom, was reported to be upset about the peace mission, which he said was not supposed to come here until some of his supporters could join it.

In his statement, which was read by aides to reporters over the telephone but not issued by the state-run media, Shariatmadari defended his party against official charges that its members were American agents, and he rejected a demand by the Revolutionary Council that the party be disbanded.

"To connect all happenings to American imperialsim will not solve any problems" Shariatmadari said in characteristic low-key fashion.

In reply to calls for the dissolution of the Moslem People's Republican Party, Shariatmadari said it has 3 million supporters, is legal and that most of its members are good Moslems.

"It seems that this government is going the way of banning all political parties by branding them either pro-American or counterrevolutionary," he said.

Khomeini, in a broadcast speech from Qom, accused "American spies" of leading Thursday night's takeover of the radio-television station here. He said files on some of the leaders of the takeover had been found in "the den of spies" -- his term for the occupied U.S. Embassy in Tehran.

Referring to the Tabriz rebels, Khomeini said. "These enemies of Islam will get their punishment."

President Carter, Khomeini said, "has been a bad president for the American people and is not qualified to be president. He disgraced America in the world. He mobilized Moslems against America.He has been a traitor to the American people. The people of America must know this and not vote for Carter."

At the Moslem People's Republican Party headquarters here, Sadreza Moghimi, a party worker, said, "Khomeini is saying these people who want freedom belong to the United States. Please take notice of me. Do I belong to the United States?"

There was great confusion tonight at the party headquarters, an old building overlooking a roundabout with a small pond in the center.

Crowds were gathered in front of the building when darkness fell, and party workers had dragged large sewer pipes across part of the road to slow down traffic. The front gates were chained and padlocked shut, and armed guards sat behind sandbagged barriers on the first floor balcony with automatic rifles trained on the street.

Inside, party workers were rushing about and handing out weapons, Moghimi told reporters he expected an attack during the night from Khomeini supporters.

"Get out, get out," he said. "Maybe they will attack here. I will see you tomorrow -- if we are alive."

In Tehran, Rahmatollah Moghaddam-Maraghei, a political leader allied with Shariatmadari, was reported still in hiding after his office was raided last week. Revolutionary authorities said the students had found his name in files in the U.S. Embassy.

The file purportedly contained a report of an interview he gave to U.S. political officers in the embassy on the situation in Iran. One of Moghaddam-Maraghei's recommendations was that the United States press for meetings with Khomeini to try to ease the strains between the two countries. He also suggested that Americans not in the government be encouraged to come here.

Among the two he suggested as representatives were Ramsey Clark, the former attorney general who met Khomeini in Paris, and Richard Cottam, a professor at the University of Pittsuburgh considered here to have been generally friendly to the revolution. One local newspaper, however, changed Cottam's name to Ricard Helms, the former CIA chief and U.S. ambassador to Iran.
