A remote-controlled bomb exploded in southern Thailand's province of Yala on Friday morning, wounding two soldiers and six local residents.
The bomb, weighing an estimated two kilograms, was detonated in front of a shop selling engine oil in Yala city, according to the Thai News Agency.
Both the military and civilian victims were rushed to hospital, where they are being treated.
The bomb squad arrived at the site to clear up and to collect evidence.
Mobile phone signals were cut off as the authorities believed that another remote-controlled device might be hidden nearby to entrap the police who responded to the incident.
The daily shootings and bombings in the three southern Thailand's border provinces of Pattani, Yala, and Narathiwat have claimed more than 2,300 lives since the violence erupted in January 2004.
