'High Likelihood' Malaysian Militant Killed in Philippine Raid

The Philippines said there was a "high likelihood" a Malaysian militant suspected of being behind the 2002 Bali bombings was killed in a controversial operation in the country's south that left 44 police dead.

Sunday's offensive against "high-value targets" including Zulkifli bin Hir -- one of the United States's most wanted militants with a $5 million bounty on his head -- turned into a bloodbath, with President Benigno Aquino ordering a probe into the incident.

Nearly 400 highly-trained Philippine policemen took part in the operation in the remote southern farming town of Mamasapano to arrest top militants -- including Zulkifli, who is also known as Marwan -- but were ambushed by Islamist fighters.

They managed to escape but strayed into territory controlled by a different militant group, sparking another firefight.

"There is a high likelihood according to the participants that Marwan was killed in the operations, but this needs confirmation," Interior Secretary Manuel Roxas told a news conference.

While they failed to recover the body of the main target, "they were able to take pictures, and these pictures will undergo a process to determine whether it was Marwan or not."

Zulkifli, among the United States's most wanted militants, is a bombmaker for the Jemaah Islamiyah (JI) group which staged the 2002 bombings in Bali that claimed 202 lives, and other deadly attacks in southeast Asia.

A top Malaysian police official on counter-terrorism told the Malay Mail newspaper that Kuala Lumpur was still waiting for information from the Philippine authorities on Zulkifli's fate.

Zulkifli, described by the U.S. State Department as a 48-year-old Malaysian militant and a member of JI's central command who had trained as an engineer in the United States, has long been sought by the authorities.

Declarations of his death, however, have proved premature in the past.

In March 2012 Malaysian counter-terror police denied a Philippine military claim that Zulkifli was killed in an air strike.

The potential success of targeting Zulkifli was blighted, though, by the police casualties, and the controversy surrounding them will likely prove a major test of a 10-month-old accord intended to end a 40-year insurgency that has claimed tens of thousands of lives.

Out of 392 "special action force" policemen who took part in the mission, 44 were killed and 12 others wounded, Roxas said.

Aquino has ordered an investigation into the Mamasapano incident, and Roxas said the head of the police special action force was relieved of his post pending an inquiry.

According to Roxas, the Philippine police were leaving the area where the operation was taking place when they were ambushed by the Bangsamoro Islamic Freedom Fighters (BIFF), a group accused of sheltering Zulkifli.

The police escaped but then strayed into territory controlled by the Moro Islamic Liberation Front (MILF), sparking another firefight, the interior secretary said.

Philippine authorities have alleged that some of the Bali bombers had fled to the southern Philippines and sought refuge with Muslim rebels waging decades-old armed campaigns against the Manila government.

They also say these militants then trained these Filipino rebels in making improvised explosive devices used in Philippine bombings.

The mainstream 10,000-strong MILF signed a peace treaty with the government in March last year, but the BIFF, a breakaway faction comprised of several hundred gunmen, was not part of the deal.

The MILF said police did not coordinate the operation as required under the ceasefire accord.

Zulkifli's group of foreign militants is alleged by the military to have also trained the Abu Sayyaf, a group of Filipino Islamic militants.

The Abu Sayyaf is suspected of being behind a car bomb in the southern city of Zamboanga last Friday that killed two people and wounded 50 others.
