Atleast four people have been killed and 23 injured in eight bomb blasts that have hit across Thailand in the past 24 hours.
Police Lt. Gen. Samer Yousamran said that four people have been killed in the explosions.
Two small bombs exploded in the popular Thai seaside resort town of Hua Hin.
The local media reported that the bombs were hidden in planters on a busy street with open-front bars.
The victims include Thais and foreign tourists, whose nationalities were not immediately known.
It was not clear who was behind the attack, but the timing suggested it might be an effort to embarrass the military government that took power two years ago.
Hua Hin is about 200 kilometres (120 miles) south of Bangkok.
