Manila - Philippine troops recovered three homemade bombs planted in a bus terminal in the southern Philippines, an army spokesman said Wednesday.

The improvised explosive devices were found Tuesday in Kabacan town in North Cotabato province, 960 kilometres south of Manila, according to Lieutenant Colonel Romeo Brawner.

Brawner said the bombs were made from 81-millimetre and 60-millimetre mortars that were attached to electric blasting caps with mechanical timers.

No suspects have been identified in the bombing attempt, but previous attacks on bus terminals in the southern Philippines have been blamed on extortion gangs victimizing bus companies. (dpa)
