Separatist insurgents shot dead three men including a village chieftain in Thailand's violent Muslim-majority south, police and relatives said on Tuesday.
The 50-year-old village head was killed at his home in troubled Narathiwat province late on Monday after eight armed militants broke in and opened fire, his wife said.
Earlier that evening in the same province, a 39-year-old former security guard was shot dead on the street and his four-year-old son shot in the leg, police said.
The child remains hospitalised in a serious condition.
In Yala province, a 46-year-old former policeman was killed Monday in a drive-by shooting.
More than 3,500 people have been killed since separatist unrest erupted almost five years ago in Thailand's Muslim-majority south.
Tensions have simmered since Thailand annexed the mainly Malay sultanate in 1902.
