"They attacked the village by using home-made bombs and set fire to some of the houses,"a local journalist said.

There are reports that some 30 homes and a church were set on fire.

Six people are reported to have been stabbed to death, and a further six are said to have died in the fires.

Christian sources say the Soya attack was carried out by a Muslim mob armed with machetes, knives and bombs.

Two of the attackers also died in the fighting.

Many of the villagers, particularly the women and children, have now fled the area.

Ambon police chief Brigadier-General Sunarko Danu Artanto confirmed the attack, but gave no further details.

Independence

The violence comes after the Christian separatist South Moluccas Republic (RMS) group raised flags in Ambon on Thursday, the 52nd anniversary of a failed independence bid.

Angry Muslim crowds took to the streets in response, and the leader of the extremist Islamic organisation, Laskar Jihad, called on all Muslims in the Moluccan islands to launch a renewed war against the Christian community.

The group's commander, Jafar Umar Thalib, told thousands attending a rally after Friday prayers that the peace agreement should be ignored.

BBC Jakarta correspondent Richard Galpin says the critical issue now is whether the authorities can prevent the violence from spreading - which would mean clamping down on the activities of Laskar Jihad, which so far the government has been afraid to do.

Muslims make up 85% of Indonesia's 210 million people, but in the Moluccas half the population is Christian.
