An explosion at an entrance of Phu Tab Berk village in Phetchabun province claimed one fatality and injured two others.
The blast at this famous tourist attraction village in Lomkao district that took place about 9am last Sunday (Sept 10).
Security authorities are investigating the incident and there is still no reports of the type of the explosive.
The victim was Suan Onta, 63, a driver of a tourist pickup truck while the injured were tourists.
The attack was designed to target officials tasked with overseeing the demolition of illegally built resorts on forestland this week, Royal Forestry Department deputy chief Atthapol Charoenchansa said on Monday.
Atthapol made the comment before meeting with national security agencies and local administrators at Phu Tab Berk to follow-up the investigation following the initial results of tests from the blast area.
The tests found that the bomb was newly made and designed to kill. That has lent weight to the belief the bomb blast is linked to the demolition of the resorts.
The explosion occurred in the area forestry officials and national security officers were slated to gather for the demolition.
The Royal Forestry Department contacted deputy national police chief General Srivara Ransibrahmanakul to request police help with the investigation and the gathering of evidence from Phu Tab Berk groups.
Atthapol said the demolitions will go ahead as planned, although those tasked with the operation to conduct their work more cautiously.
