One person was killed and seven others injured when suspected insurgents detonated a bomb at a market in Thailand’s violence-prone south today, police said.

An Islamic leader accused Thai troops of overreacting in a crackdown on rioters that left six people dead, while a military commander said 1,300 people were arrested in the rioting in Thailand’s Muslim-dominated south.

Security forces fired shots in the air and used water cannons and tear gas to disperse about 2,000 angry Muslim youths rioting in Thailand’s troubled south today.
