Insurgents killed two policemen in the Muslim-dominated south of Thailand on Saturday and a bomb wounded three people, including a Malaysian, in the latest attacks in the restive region, police said. The policemen were on duty in a market in the southern province of Yala when two gunmen opened fire, killed the officers and stole their weapons, a police official said. In another incident on Saturday, a bomb exploded at a tea shop and slightly wounded three people in the town of Sungkai Kolok, on the border with Malaysia, police said. "One of them is a Malaysian and other two are the tea shop owner and a customer," a police spokesman told Reuters.
