Hostage negotiations ruled out

MANILA, Philippines (CNN) -- A top security chief has rejected the possibility of negotiating with Abu Sayyaf guerrillas holding an American missionary couple.

Philippine National Security Adviser Roilo Golez rejected the list of demands and said that neither the Philippine government nor the United States would negotiate.

Golez accused the Abu Sayyaf of trying to "sanitize" the kidnapping of the couple and cloak it in political legitimacy by linking it to other Muslim causes.

"I think they have no political agenda. They are not fighting for any lofty cause. They are just there for money and to instil terror as part of an international terrorist group," Golez said after a meeting with Assistant U.S. Secretary of State, James Kelly.

"No ransom. No other conditions. No concessions. If they want to surrender the Burnhams, they can do so unconditionally," Golez said.

The kidnapped couple, Martin and Gracia Burnham, were seen in a videotape, released Thursday, reading out what appeared to be a list of demands and confirming the Abu Sayyaf's ties to Al Qaeda.

Although the video gives hope that the couple could be rescued alive, a military spokesman said there were signs the footage was old.

The videotape of the Burnhams showed them looking healthy while they read a statement from Abu Sayyaf, the militant rebel group holding them hostage in the Philippines.

But the couple's mission told CNN it believes it is an old videotape.

With hooded, armed rebels in the background, Martin and Gracia Burnham appear in the forefront of the video, released by Reuters news agency. In it, Martin reads a statement that says their captors are targeting Americans, Europeans and other Westerners because of U.S. policies in the Middle East. (Full statement)

Scott Ross, a spokesman for the New Tribes Mission, said: "We're not seeing it as a new video."

Ross told CNN in a telephone interview that upon careful examination, he and others believe the video has a number of inconsistencies, including:

Reuters reported that the cameraman, who identified himself as a former Muslim rebel, would not say exactly where he shot the video.

He told Reuters he made the tape in mid-January after being granted access to Abu Sayyaf's hideouts in the islands of Jolo and Basilan. His statements could not be independently verified, Reuters reported. The video statement indicates Abu Sayyaf believe they are in league with al Qaeda.

U.S. Special Forces have joined Filipino patrols in the jungles of Basilan, where the Islamic extremist group has been holding the U.S. couple and a Filipina nurse hostage. The joint mission, aimed at wiping out Abu Sayyaf, is part of the U.S.-led war on terrorism. (More on U.S. deployments in the war on terror)

The United States has put Abu Sayyaf on a list of terrorist groups with suspected links to the al Qaeda network of Osama bin Laden.

The Burnhams, from Wichita, Kansas, were snatched last year along with American Guillermo Sobero and 17 Filipinos.

Sobero, a Californian native, was beheaded. His remains were uncovered by Filipino troops near the Abu Sayyaf's jungle post in Basilan province.

The other 16 Filipinos were later released.
