Thirteen people, most of them students, were killed when a pick-up truck flipped over while trying to change lanes on Sunday in the Thai capital,
police said.
Graphic CCTV footage shows passengers riding in the back being hurled out of the vehicle onto the road in Bangkok's suburbs.
"Twelve people died instantly and one later died at the hospital," police officer Samran Chaytao told AFP, adding that nine of them were college-age students finished mechanical training for a local company.
