The fire broke out at about 1pm after the air-conditioned bus was about 200 metres beyond the Sukhumvit 62 expressway gate. The entire bus was engulfed by the flames, shocking tourists who lost their bags in the bus compartment. With a section of the expressway gate closed so firefighters and fire engines could battle the blaze, vehicles piled up for the over two kilometres to the Bang Na gate. Pirapong told the tour guide to tell the tourists to flee and the fire quickly engulfed the bus. Several tourists wept to see their belongings go up in flames, the bus driver recounted.
