At least four people were injured when a time bomb was detonated at a food store in Thailand's violence-plagued southern province Narathiwat on Wednesday morning, local radio reported.
The bomb, estimated at about two kilograms, was contained in an iron box put in front of the food store in Narathiwat's Rueso district, according to traffic radio channel FM 100.
Four people, including the food store owner and customers, were injured by the bombing and sent to hospital.
Insurgency-related violence, including roadside bombings, drive- by shootings and arson attacks, is reported almost daily in Thailand's three southernmost provinces -- Narathiwat, Yala and Pattani. Over 2,100 people have been killed in more than three years since insurgency resurged in the region in January 2004 when militants raided an army ammunition depot.
