Two people were wounded in a motorcycle bomb blast in a village in southern Philippines' Sulu province Saturday night, the military said on Sunday.

The victims, a 35-year-old lady and a 2-year-old baby boy, were sent to hospital soon after the blast, said Alan Arrojado, commander of the joint task group in Sulu.

Initial investigation showed that the motorcycle was parked by two unidentified men at around 5:30 p.m. and the blast had partially damaged the wooden fence of a karaoke bar.

No organization has claimed responsibility for the blast so far. Police investigation is still going on.
