No witnesses have said there were U.S. forces on the ground when the killings occurred, and Schinnerer said that none were. She also said that intelligence gathering does not violate a prohibition against U.S. forces engaging in combat here.
The human rights commission report recommending criminal and administrative proceedings against troops and officers involved in the operation was written before a Times reporter informed the panel of Rafael's account of U.S. surveillance. The commission gets its mandate from the Philippine Constitution.
Asked whether the U.S. military would assist Philippine authorities in any prosecution arising from the assault, Schinnerer said, "It would be inappropriate to speculate on what remains a hypothetical situation." But, she added, "as a general rule, the U.S. would provide such support to the [Philippine government] if asked."
Under the Philippine Constitution, the hundreds of U.S. military advisors in the southern Philippines are not allowed to engage in combat while helping train local forces in the hunt for militants with Abu Sayyaf and the Indonesia-based Jemaah Islamiah. Both groups are allied with Osama bin Laden's Al Qaeda network.
The guerrilla force that Rafael said the Orion spotted would have been unusually large for Sulu. No insurgents were captured, wounded or killed approaching the village, according to the military's accounts. A small arms cache, including a .45-caliber handgun, an M-16 assault rifle and some rifle grenades were seized in the raid, Rafael said.
Two soldiers were killed and five wounded in the Ipil operation, statistics the army cites as proof of a battle with militants. Villagers contend that the soldiers were killed in their own crossfire. Commission investigators found that was a possibility, but suggested Wahid may have opened fire on the troops as they swarmed around his house.
The Philippine military said an internal investigation had cleared its troops of any wrongdoing, which many here see as a whitewash.
While condemning the findings, attorney Jose Manuel Mamauag, regional director of the Commission on Human Rights, said he was glad the military had issued its conclusions, allowing the commission to take the next step.
"Definitely, we will file charges against the soldiers," Mamauag said.
Sulu Gov. Tan, taking a rare stand against the powerful military, has directed provincial officials and police to build a separate criminal case against as yet unidentified soldiers and commanders involved in the Ipil assault.
