Roadside bombs in southern Thailand killed one police officer and wounded seven members of the security forces in a region scarred by a long-running separatist insurgency, Reuters cited police as saying on Sunday. The dead officer was part of a bomb disposal team that caught in a secondary blast while attending the site of an earlier bomb attack on Saturday night, police Lieutenant Preecha Prachumchai told Reuters. Four of his colleagues were wounded in the explosion. Since 2004, more than 6,500 people, most of them civilians, have been killed in violence in Thailand's three southernmost provinces' militant insurgency.
