MANILA, Philippines (AP) — The Philippine president is warning of a possible terrorist attack in the south and say security has been beefed up in the volatile region.

President Benigno Aquino III’s spokesman says Aquino called Mayor Rodrigo Duterte of the port city of Davao on Sunday to relay details of the threat and call for heightened public vigilance.

Coloma did not release details of the threat, but a military intelligence official told reporters that a Muslim rebel with links to the Indonesia-based Jemaah Islamiyah militant network, Basit Usman, is believed to be planning to attack Davao or two other southern cities with a car bomb and home-made explosives.

The plot could be in retaliation for a recent government assault that killed two of Usman’s associates and led to the arrest of his wife.
