BANGKOK — Suspected militants detonated a bomb under a train in Thailand's insurgency-riven deep south Sunday, leaving one person dead and 15 wounded, police said. The device, which killed a defense volunteer, was buried under the railway in the flashpoint district of Rueso in Narathiwat, one of several Muslim-majority border provinces plagued by an eight-year conflict. The wounded included passengers and railway employees. No foreigners were thought to have been on board the local train, which was severely damaged in the blast. — AP
