Suspected Abu Sayyaf member was on board Philippine vessel and is missing
Philippine authorities fear last week's ferry disaster may have been caused by the country's first suicide bombing, fanning fears of more such attacks as May's presidential elections loom.
House of Representatives foreign relations committee chairman Apolinario Lozada said it was 'highly possible' a suicide bomber from the Muslim extremist Abu Sayyaf group was behind an explosion and fire that gutted the Superferry 14 last Friday.
The disaster killed two and left 134 of its 899 passengers missing.
The possibility of a suicide bombing led to fears about attacks against election candidates and ordinary Filipinos.
'We should start looking at all possible angles that could give them [the terrorists] media exposure, which is what they're after,' Mr Lozada said.
