BANDA ACEH, Indonesia (AP) _ Indonesian police arrested three top separatist negotiators Friday, just days after peace talks broke down in Aceh province, witnesses said.

Police refused to comment on the arrests, which were made at a hotel in the provincial capital, Banda Aceh, where talks about setting up a joint peace task force stalled Wednesday.

The detainees were Nashiruddin Ahmad, Amni Ahmad Marzuki and Amdi Hamdani. All were representatives of the Free Aceh Movement, which has waged a guerrilla war against Indonesian rule for the past quarter century.

Witnesses said dozens of heavily armed officers raided the Kuala Tripa Hotel where the men had been staying. They said the three men were driven away in three unmarked cars to city police headquarters.

The three-day meeting between the two sides ended Wednesday with no agreement on a proposal to establish a joint committee to supervise a cease-fire agreement.

The talks had been sponsored by the Geneva-based Henry Dunant Center, which has mediated in discussions between the two sides in Switzerland over the past 18 months.

A representative of the center, which specializes in conflict resolution, witnessed Friday's arrests and attempted to stop the rebel negotiators from being taken into custody.

``We have no business with you,'' a police officer said when the representative tried to intervene. ``This is between us and the rebels.''

In Jakarta on Thursday, Indonesia's parliament passed a new law granting Aceh's local government extra powers in an effort to placate growing separatist demands.

Aceh, about 1,100 miles northwest of Jakarta, has been wracked by escalating violence in recent months.

More than 900 people, the majority of them civilians, have been killed in the conflict so far this year. International human rights groups blame government forces for most of the deaths.

During the past 10 years, more than 6,000 people have died in the conflict.
