MANILA, Philippines -- (UPDATE) A Jemaah Islamiyah (JI) militant who allegedly masterminded the 2002 Bali bombings eluded arrest during a military raid at dawn on Thursday, the spokesman for the military said.

But an Abu Sayyaf sub-commander, Radi Upao, was killed in the encounter in Balimbing town, Tawi-Tawi province, said Lieutenant Colonel Bartolome Bacarro, Armed Forces public information officer.

A composite team of Marines from the Force Reconnaissance Battalion, Navy commandos, and intelligence operatives swooped down on the extremists' lair at 5:10 a.m., Bacarro said in a text message to reporters.

"The encounter resulted to the killing of ASG [Abu Sayyaf Group] sub-leader Radi Upao, while Dulmatin was able to escape," Bacarro said, citing initial reports.

Upao carries a $160,000-reward for his capture. Dulmatin, on the other hand, carries a $10-million bounty.

Bacarro could not confirm if Dulmatin was with another fellow suspect in the 2002 Bali attack, Umar Patek, who is also affiliated with the JI, the Southeast Asian arm of the Al Qaeda global terror network.

Earlier, the military said that Dulmatin, Patek, and the remaining Abu Sayyaf leaders were holed up on Jolo Island.
