Three hidden roadside bombs have killed two people and wounded 13 others in southern Thailand, and police believe Islamist militants are responsible.
Police Col. Nitinai Langyanay said the first bomb in Narathiwat province killed two irrigation workers Friday and wounded five others, while a second one about 1 kilometer (one-half mile) away wounded a soldier.
Bomb removal officers then tried to defuse a third bomb only three meters (yards) away from the second one but it exploded, wounding seven policemen. It is a standard practice of the insurgents to plant a second bomb to go off when security officials arrive to investigate an explosion.
More than 4,300 people have been killed in Thailand's three southern provinces since an Islamist insurgency flared in 2004.
