Bangkok: Three Thai policemen were killed and two wounded on Friday in a bomb and gun attack in the southern province of Yala where Muslim separatists have been waging a simmering insurgency against the state.

The attack came just over a month after a series of bombs in three of Thailand's main tourist towns killed four people and wounding dozens and raised fears the insurgents were expanding their fight to tourist targets.
