"Elements from the army's 29th Infantry Battalion conducting blocking patrol in the guerrillas'possible route of withdrawal found the suspects inside three makeshift huts in nearby Mabuhay village," said Osias.

He said no casualty was reported on both sides following the five-minute fire fight.

The military spokesperson said troops also recovered from the suspects a U.S.-made Thompson submachine gun, a 12-gauge shotgun, pieces of ammunition and communication paraphernalia.
