WASHINGTON (Reuters) - The family of a U.S. hostage being held in the Philippines said on Wednesday the FBI told them it was very likely he was a victim of "foul play" but his relatives clung to the slim hope he was still alive.
Muslim rebels holding Guillermo Sobero along with two other U.S. citizens and 17 Filipinos, said Tuesday they had executed him. Two headless bodies were found but officials identified both bodies as those of local men.
Alberto Sobero, brother of the hostage, told ABC's "Good Morning America" program that the U.S. State Department told them it could take several hours to days before the two bodies could be positively identified.
"The FBI has told us that the likelihood that he (Guillermo) has met foul play is now very high," added Sobero from his home in Cathedral, California.
The rebels seized Sobero, an American missionary couple and 17 Filipinos from a beach resort near Palawan island on May 27. After escapes, rescues and fresh seizures, they now hold more than two dozen hostages.
Alberto Sobero said he was still clinging to the hope his brother was alive.
"That's all we have left now is just hope. If indeed they have killed him they have left four children without a father and a grieving mother. We are still clinging to that very slim hope that he will return," Sobero said.
Aimee Sobero, 13, and the eldest of the hostage's four children, also appeared on the program. She said her other siblings, aged 6, 3 and 2, had been told only that their father was away working.
The teen-ager, who has previously made personal appeals to the hostage-takers to release her father, said he would never have gone on a diving holiday in the Philippines if he had known the danger that faced him there.
"If he would have known something bad was going to happen to him and cause such grief to the whole family, he wouldn't have gone," she said.
In a separate interview with CBS News "The Early Show", Aimee said she had written to President George W. Bush asking for his help.
"All I know is that we really needed his help, because he's the boss, pretty much, and without him, nothing's possible, really," said the teen-ager.
Alberto Sobero said if the Muslim rebels had harmed his brother, then maybe it was time for the Bush administration to change its policy of not intervening in such situations.
"If they have in fact harmed my brother then maybe it is time for the Bush administration to change the way it has been handling the situation," he said.
The Abu Sayyaf rebels holding the hostages say they are fighting for Muslim self-rule in the south of the Roman Catholic Philippines.
