Manila: Four foreign terrorists were killed in southern Philippines last week, but only two prominent members of the Al Qaida-linked Jemaah Islamiya were identified following a Philippine Navy's air strike, according to a newspaper report.

Hajan and Saad, who had one name each, were Indonesian nationals and members of the Jemaah Islamiyah who were "believed to have been |killed" by the Philippine Navy's air strike on the Abu Sayyaf Group's lair in Duyan Kabau village, Parang town Sulu last Thursday, Western Mindanao Command (Westmincom) chief Maj. Gen. Noel Coballes told the Star.

"The Western Mindanao Command will provide the necessary support if it is a government-to-government agreement (that will be forged by the Philippine and Malaysian government, for the purpose of identifying one of the four foreign terrorists)," said Coballes, adding that Malaysian authorities were sending representatives to Mindanao soon.

Philippine and Indonesian authorities could also forge an agreement to allow authorities of both countries to cooperate and identify the bodies of Haian and Saad, another source told Gulf News.

At the same time, Singaporean authorities could be planning to send a representative since one of the killed terrorists in last week's incident, was alleged as Singaporean, the same source said.

Philippine authorities have identified only 11 Abu Sayyaf members out of the 15 terrorists who were killed during the air strike, Coballes admitted.

"The military has yet to secure the bodies of the slain terrorists. Militants were believed to have retrieved the bodies of their casualties and buried them hastily," the Star said, but did not attribute the statement to anyone.

The two other foreign terrorists whose bodies must be identified were named by authorities as Zulkipli bin Abdul Hir, also known as Marwan, a US-educated Malaysian engineer who became Jemaah Islamiya's top leader; and Muhamda Ali, also known as Muawiya, a Singaporean.

Marwan organised Malaysia's Kumpulun Mujahidin Malaysia, an alleged terror group.

Marwan trained members of the Abu Sayyaf in bomb making after hiding in the southern Philippines after the bombings that killed 200 in bali, Indonesia in 2002.

Marwan was the alleged associate of Umar Patek, also a Jemaah Islamiyah leader who hid in the south in 2003. He eluded arrest when he escaped from the southern Philippines and went to Abbottabad, Pakistan before Al Qiad leader Osama bin Laden was killed in 2010.

Marwan had a $5 million bounty issued by the US Federal Bureau of Investigation.

At the same time, Ali, the Singaporean, was Jemaah Islamiyah's senior leader involved in the Bali bombing. He also had a price of $ 50,000 on his head.

Also killed was Philippines' Abu Sayyaf leader Gumbahali Jumdail, alias Dr. Abu Pula, one of the group's founding leaders.

Jumdail was allegedly behind the beheadings of the group's kidnapped victims.

The Abu Sayyag Group has been blamed for high profile kidnappings of foreigners in 2000 and in 2001.

Philippine authorities blamed it for kidnap-for-ransom, beheadings, bombings and other terror activities in the south and also in Metro Manila.

It was established in the 1990s, with funds by a non-government organisation that was organised by Bin Laden's relative in the south.
