More than a dozen armed men abducted a naturalized American, her teenage son and Filipino nephew before dawn Tuesday from a southern Philippine island near a stronghold of al-Qaida-linked militants, officials said.
Suspicion fell on the notorious Abu Sayyaf, which has been blamed for ransom kidnappings, beheadings and bombings in the last two decades, or a Muslim rebel commander whose group has been linked to previous abductions.
