Philippine troops have killed a leading Islamist militant wanted by the US after raiding his safe house in the south of the country, officials say.
Mobin Abdurajak, said to be a senior leader in the Abu Sayyaf group, was wanted for the abduction in 2000 of 21 people from a Malaysian resort.
Regional officials said he died in a shootout when marines swooped on his hideout in the island of Tawi-Tawi.
The United States had offered $20,000 (£9,900) for his arrest.
Mobin Abdurajak was a brother-in-law of Abu Sayyaf chief Khadaffy Janjalani, who was killed in a clash with Philippine troops last year.
"The neutralisation of Abdurajak is part of our campaign to eliminate the Abu Sayyaf terrorists," regional navy chief Emilio Marayag said, according to the Reuters news agency.
In the mainly Catholic Philippines, Abu Sayyaf is the most notorious of several active Muslim rebel groups.
Last week, 14 of its members were jailed for life for abducting 20 people from a luxury beach resort in the western Philippines in 2001.
Three of the victims, including an American, were decapitated.
