BANGKOK: Thai police hunting the culprits behind a wave of deadly blasts that rocked tourist destinations and killed four said on Sunday they “know who was behind” the attacks. Police said two men have been held for questioning over the blasts in Hua Hin -- a resort town struck by four bombs -- with a third questioned over a suspected arson attack in Nakhon Si Thammarat province. Officers, who have ruled out terrorism, said the investigation was preliminary and refused to identify the detained as suspects, or offer a possible motive. Some analysts suggest the blasts are most likely connected to a simmering insurgency in Thailand’s southern tip, pitting Muslim rebels against the state, but police have said foreign or local terrorist groups were not behind the attacks and have instead labelled them act of “local sabotage.”
