At least three people were killed and two others injured in two separate shootings in south Thailand \'s Narathiwat Province on Sunday, local media reported. Three people were shot dead by insurgents in a grocery store in Narathiwat, Thai media The Nation quoted police as saying. Four insurgents came to the store on two motorcycles, pretending to buy goods. They shot a woman in front of her 8-year- old son. They killed the woman\'s father-in-law and a customer in the store, according to the report. In a separate case, a gunman on a motorcycle shot at two government employees in Narathiwat\'s Rueso district, injuring both of them. The injured were sent to hospital. The shootings followed a series of bomb attacks last week. Last Tuesday, at least three people were killed in seven bombings in Yala Province, neighboring Narathiwat. Last Sunday, a shooting and two bombings killed at least seven people, including two soldiers. More than 4,800 people have died in conflicts in southern Thailand for the past eight years.
