Sri Lanka's military says troops have recovered another submarine-type craft in an area formerly controlled by the defeated Tamil Tiger rebels.

Military officials say the submersible vehicle, capable of carrying a crew of three, was found late Saturday submerged about 500 meters off the coast of the northeastern district of Mullaittivu.

Several submersible devices had been found by the military in the final phase of Sri Lanka's decades-long civil war that ended two months ago with the defeat of the Tamil Tigers and the death of the group's leader, Velupillai Prabhakaran.

Last week, the troops uncovered a large arms cache in the same district, containing more than 300 roadside bombs and huge quantities of ammunition.
