The bus carrying six teachers and 39 students in elementary and junior high school was travelling from Uthai Thani province, about 300 kilometres (186 miles) north of Bangkok, for a school trip in Ayutthaya and Nonthaburi provinces on Tuesday.

The fire started while the bus was on a highway north of the capital and spread so quickly many were unable to escape.

Trairong Phiwpan, head of the police forensic department, said 23 bodies were recovered from the bus.

The recovery work and confirmation of the total dead had been delayed earlier because the burned vehicle, which was fueled with natural gas, remained too hot to enter for hours.

A real tragic accident that could have been be avoided just by doing a quick checkup on the bus.
