A motorcycle bomb exploded in a market in Thailand's southern Yala province on Monday, killing three people and wounding 22, a spokesman for the Internal Security Operations Command (ISOC) said, the first such attack in the region in months. "The criminals put a bomb in a motorcycle and placed it next to a market cart. The force of the explosion caused three people to lose their lives," said ISOC spokesman Pramote Prom-in.
