In Thailand, three policemen were killed and other two police officials injured, one of them critically, in a bomb and gun attack. Police said the incident occurred in the southern province of Yala, where Muslim separatists have been waging insurgency against the state. Police Lieutenant Colonel, Chamnan Bhutpakdee said, police were travelling in two pick up trucks when the first vehicle was blown up by a road side bomb, killing three policemen. Insurgents then opened fire on the second vehicle, injuring two officers. <br/><br/>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.
