Three policemen were killed on Wednesday in a bombing in Thailand's insurgency-wracked south, police said, while two people were killed in other separatist violence.
Militants detonated the 20-kilogram (44-pound) device by remote control shortly after midday near a bridge in Yarang district of Pattani province after they lured the police by setting fire to a telephone booth, police said.
Six police officers and two villagers were caught in the blast, and three policemen later died in hospital, said Wattana Wattanayagorn, director of Yala provincial hospital where the victims were being treated.
