A bomb has exploded at a morning market in southern Thailand, killing a Buddhist man and wounding at least seven other people.
The blast in the Tanto district of Yala province came hours after at least two bombings in neighbouring Narathiwat.
The violence is the latest to hit the mainly Muslim southern provinces.
At least 500 people have been killed in clashes between security forces and militants this year, including at least 85 Muslims at a protest last month.
The army said they died in the aftermath of a demonstration in Narathiwat, 78 of them after they were overcrowded into army trucks following their arrest.
More than 20 people, including Buddhist civilians, have been killed in apparent revenge attacks by suspected Muslim militants.
The device, believed to have been triggered by a mobile
phone, exploded at the market around 0700 (0000 GMT), a local policeman said.
The latest blast followed a bomb in the capital of Narathiwat on Friday, which injured at least 14 people.
A police spokesman said someone pretending to be a customer left a bomb in a bag at the restaurant and detonated it after leaving.
Security has been tight across the region
In a neighbouring province a teacher was shot dead from the back of a motorbike.
Prime Minister Thaksin Shinawatra pledged to use a mix of peaceful
means and force to resolve the crisis in the region.
"We really wished to solve the problems by peaceful means.
But some people have still used violent ways, so we have to use
both ways," Mr Thaksin said in his weekly radio address.
Thailand's Muslim population has long complained of discrimination by the authorities in Bangkok.
But the security situation has been deteriorating since the start of this year, with almost daily attacks which the authorities have blamed on Muslim separatists.
