JOLO, Philippines (AP) -- Officials say a homemade bomb has killed two people and wounded 13 others on a troubled southern Philippine island where al-Qaida-linked militants are active.
Acting Sulu provincial Gov. Kadil Estino says the bombing late Saturday was carried out by the militant Abu Sayyaf group in retaliation for the killing of a member by the military in a clash three days earlier.
Police Chief Glenn Roy Gabor in the provincial capital, Jolo, says the bomb was placed in front of a grocery store that is a favorite shopping place for Philippine marines.
The shop was closed and most of the victims were bystanders in a nearby park.
The Abu Sayyaf is on Washington's list of terrorist groups and has been blamed for numerous kidnappings, beheadings and bombings.
