MANILA Filipino Islamic militants were likely behind an attack on a Vietnamese cargo ship in which one crew member was killed and six others abducted, Philippine Foreign Secretary Perfecto Yasay said Tuesday. The MV Giang Hai was hit by unknown gunmen Sunday near the southernmost Philippine island of Baguan near the Malaysian coast."We can only assume that they were taken by Abu Sayyaf people but this has to be verified," Yasay told a news conference aired live on television.
