Robin Mcdowell, Peudada – Acehnese rebels emerged from their jungle camps Friday to surrender a second batch of weapons, as the guerrillas and the Indonesian government argued over what kind of guns should count under their peace deal.

The decommissioning of the rebels' armory is viewed as the most sensitive element of the accord, Aceh province's best chance in years of ending three decades of fighting that has claimed 15,000 lives. The guerrillas Thursday surrendered 78 aging firearms to the E.U-led monitoring mission, but 17 were rejected after they were judged not in useable condition, said Juri Laas, a spokesman for the mission.

The rebels have agreed to surrender a quarter of their 840 weapons – a figure provided by the separatists themselves and agreed to by the government – by Saturday and the remainder by the year end.

Indonesian Maj. Gen. Supiadin said homemade weapons, typically primitive single-shot guns, shouldn't count toward the final figure. Rebel commanders disagreed, saying all weapons should be included.

The accord, agreed to in Finland last month, does not specify the type of weapons to be handed in. Laas said homemade weapons did count under the deal so long as they were fireable. He said that disagreements over the details of the process were "no surprise," and that "we are well on track" for Saturday's deadline to be met.

The insurgents Friday handed in a second batch of 109 weapons to monitors in the village of Peudada in the north of Aceh province, witnesses said. They were mostly aging AK-47s and other assault rifles. They were to be examined and cut into pieces.

In exchange for the rebels disarming, the Indonesian military is to more than halve the 60,000 security forces it has in the province, with roughly 7,000 troops scheduled to be pulled out after the first 210 guns are handed in.

Efforts to end the 29-year civil war picked up pace after the Dec. 26 tsunami crashed into coastlines, killing 131,000 people in Aceh and leaving half-million others homeless.

The rebels and the Indonesian government returned to the negotiating table, saying they did not want to add to the people's suffering, and hammered out an agreement.

Both sides made major concessions. The rebels gave up their long-held demand for independence and the government agreed to give the region a limited self-government and control over 70% of the revenue from the province's mineral wealth.

An earlier agreement broke down in 2003 amid disagreements over its terms and repeated violations by both sides.
