A roadside bomb killed four paramilitary rangers on an intelligence-gathering operation in insurgency-plagued southern Thailand, the army spokesman said Thursday, according to AP. The rangers were returning to their base in a pickup truck when the bomb detonated in Pattani, Col. Parinya Chaidilok said. «The insurgents buried a fire extinguisher that contained explosives on the roadside,» Parinya said. «We believe the rangers were targeted because they were gathering intelligence for the army.» There was no immediate claim of responsibility.
