The Nation newspaper said the teachers were trapped in the burning vehicle after the Friday night crash on a highway in Chonburi, southeast of Bangkok. The Khaosod newspaper said the victims were school teachers.
The Nation reported the driver lost control after one of the tires of the van burst. It quoted the interior ministry’s disaster management department as saying that four people managed to get out of the van before it burst into flames.
Thailand roads are among the world’s most dangerous. Speeding and other traffic violations are common and law enforcement on the highways is lax.
