BAGHDAD, Iraq - The interim prime minister said Monday he would not interfere with an Iraqi tribunal's right to decide whether Saddam Hussein and his top lieutenants should be executed on war crimes charges, the Arab language television station Al-Arabiya reported.

Prime Minister Iyad Allawi said he was willing to abide by whatever the court decides in the trial, which is not expected to begin for months. Iraq assumed legal custody of Saddam from the United States last week and reinstated the death penalty, which had been suspended by U.S. occupation authorities.

"As for the execution, that is for the court to decide - so long as a decision is reached impartially and fairly," he said.

Saddam's first court appearance Thursday dominated the media across Iraq. The broadly outlined charges include the slaughter of Shiites during a 1991 uprising and a chemical weapons attack against Kurds in the northern city of Halabja.

Thousands of Kurds demonstrated today in Halabja, demanding that Saddam and one of his key lieutenants - Ali Hassan al-Majid, also known as "Chemical Ali" - be put to death for the gas attack that killed 5,000 people on March 16, 1988. Carrying photos of their slain loved ones, the marchers said they want Saddam to be tried and executed in their town.

"Every family in this city lost no less than five of its dear sons," said demonstrator Sabiha Ali, 50. "Therefore, we want to execute Saddam on the soil of the land."

Iraq has been wracked by lawlessness and violence since the fall of Saddam's regime 14 months ago.

Iraq's oil exports were cut nearly in half as workers struggled today to repair a key pipeline shut down after looters sabotaged the line, according to officials with the South Oil Co. and traders.

The looters, trying to steal crude oil for sale on the black market, breached one of the country's two key southern pipelines, said an SOC official, speaking on condition of anonymity.

Also today, a land mine detonated along the main route to the southern city of Samawah, where Japanese troops are based, police said. There were no reports of injuries. The route is frequented by coalition forces.

In southern Iraq, insurgents fired rockets at a government building early today, but instead struck nearby homes, wounding eight, police said. The attack targeted the province's main offices near the center of the Basra.

Interior Ministry officials also said two Iranians suspected of trying to detonate a car bomb were captured, but gave no details.

Iraqi officials have blamed foreign fighters and religious extremists for a wave of recent vehicle bombings. The attacks have led to fears that religious fanatics and Saddam loyalists may be joining forces to fight both the multinational force and the new Iraqi government.

Iraqi troops thwarted a car bombing outside their regional headquarters northeast of Baghdad on Sunday, killing an attacker before could detonate his vehicle. Two bystanders also died in the assault in Baqouba, the scene of fierce fighting last week between American soldiers and insurgents who tried to seize government buildings and police stations.

Also in Baqouba, gunmen fired at a building belonging to a city council official in the town of Khalis on Sunday, killing two people and wounding two, said Salih Mahdi, the spokesman for the Diyala province.

Iraqi government officials have suggested that tough moves will soon be taken to combat the violence, but canceled a news conference today where they had been expected to announce a limited amnesty for insurgents and martial law in parts of the country.

The news conference with Justice Minister Malik Dohan al-Hassan and Human Rights Minister Bakhtiyar Amin was postponed indefinitely just as it was scheduled to begin. The government had canceled a previous news conference on the same topic.

Britain and Australia offered support today for the proposed amnesty offer. Britain's Foreign Secretary Jack Straw and Australian Foreign Affairs Minister Alexander Downer agreed that the interim Iraqi government was entitled to make such decisions.

The delay in deciding on security measures came hours after Muqtada al-Sadr, a militant Shiite cleric whose April uprising left hundreds dead, issued a defiant statement calling the new interim Iraqi government "illegitimate."

"We pledge to the Iraqi people and the world to continue resisting oppression and occupation to our last drop of blood," al-Sadr said in the statement from his office in the Shiite holy city of Najaf. "Resistance is a legitimate right and not a crime to be punished."

Previously, al-Sadr had made conciliatory statements to the new government of Allawi, a fellow Shiite, and members of his movement had suggested they might transform the al-Mahdi Army into a political party. Al-Mahdi fighters accepted cease-fires in most Shiite areas after suffering huge losses at the hands of the Americans.

It was unclear what prompted his apparent reversal, though al-Sadr has made contradictory statements in the past.

In his statement Sunday, the young cleric said, "There is no truce with the occupier and those who cooperate with it."

"We announce that the current government is illegitimate and illegal," he said. "It's generally following the occupation. We demand complete sovereignty and independence by holding honest elections."

Earlier Sunday, Allawi told ABC News that he had met with al-Sadr representatives "who want to try and mediate."

"The position of the government is very clear," Allawi said. "There is no room for any militias to operate inside Iraq. Anything outside law and order is not tolerated, cannot be tolerated. The rule of law should prevail."

Al-Sadr's harsh statement suggested the government may be taking a hard line with him, insisting he abolish his militia and submit to the warrant.

Although Iraq regained sovereignty June 28, about 160,000 foreign troops, most of them Americans, remain under a U.N. resolution to help the new government restore security.
