One person was killed and 30 wounded when two bombs exploded late on Tuesday near a hotel in the southern Thai beach town of Pattani, police said, less than two weeks after a series of blasts hit the south.

The first blast in a car park behind the Southern Hotel caused no casualties, Police Lieutenant Colonel Winyu Tiamraj said on Wednesday.

"The second explosion came from a truck parked at the hotel entrance, opposite a karaoke bar and a massage parlour, resulting in one death and 30 injuries," he said. All the casualties were Thais.
