"Two of the victims were killed at the scene, while the other died at a hospital,” he told reporters here. The number of injured is expected to increase.

The unrest in southern Thailand, especially in the Yala, Pattani dan Narathiwat provinces began in 2000 and has since claimed the lives of more than 7,000 people and thousands were injured.
