The twisted remains of a tour bus and truck collision that killed at least 43 in Veracruz, Mexico.
Authorities say the bus was hit by a truck after its trailer somehow became decoupled, as the vehicles passed in opposite directions on Friday morning.
Another truck then crashed into the bus, investigators said.

"Unfortunately this is a tragic accident. A truck with a double cargo trailer decoupled and the driver tried to manoeuvre to miss the bus."
The bus was transporting workers north, likely to factories along the U.S.-Mexico border.
Officials are also arranging transportation for relatives to be with the survivors, including three teens in serious condition, as well as identify the bodies of loved ones.
