The four senior Shia Muslim clerics in Iraq have said that armed resistance is not the way to protest against the continued presence of US-led forces.
After weeks of fighting, calm has returned to Najaf's Imam Ali shrine
However, one of them, Sheikh Ali Najafi, said that if foreign troops stayed too long, then the time for peaceful solutions would be over.
The clerics met at the home in Najaf of Grand Ayatollah Ali Sistani.
Despite their comments, Saturday has seen another day of violence in both Shia and Sunni areas of Iraq.
The meeting of the group known as the Marjaiya came two days after Ayatollah Sistani's intervention ended a three-week long uprising in Najaf by Shia militiamen loyal to dissident cleric Moqtada Sadr.

Sheikh Najafi, the fourth cleric in the Marjaiya quartet, arrived later
for a separate audience with Ayatollah Sistani.
BBC Baghdad correspondent Matthew Price says Iraqi Shia Muslims will listen to words of the senior clerics, and most will follow them.
Saturday saw the city of Najaf peaceful, but in Sadr City, a Shia city of the capital Baghdad, militants clashed with US troops.
A health ministry official said three
people were killed and 25 were wounded in the skirmishes.
In eastern Baghdad, insurgents fired a round of mortars
into a crowded neighbourhood, reportedly killing two
boys washing cars.

Meanwhile, a team of ministers from Iraq's interim government has gone to Najaf to meet Ayatollah Sistani, and discuss plans to rebuild the city.
They arrived in two US Black Hawk helicopters and were driven to the Imam Ali shrine, the centre of the uprising.
Correspondents say the ministers found a city with its buildings pockmarked with bullet holes, and streets littered with wreckage and ammunition.
The Minister of State, Kasim Daoud, who led the delegation, said they had come to Najaf to congratulate Ayatollah Sistani and to consolidate the peace agreement.
