Pol Maj-General Pornchai Suteerakune added that forensic police would collect DNA samples from the relatives of 18 people reported missing to see if they might be among the victims.
This would take time, he said, as there are many separate bones at the sites. He also admitted that the condition of old and burnt bones might hamper the effort to compare DNA, but he said the forensic work would be done as fast as possible because the news had received a lot of public attention.
