At least seven people have been killed and many more injured after a Greyhound bus was involved in a horrific head-on crash, which saw two vehicles ripped in half.
"Many passengers with serious injuries were transported to a nearby hospital", the state police said on Twitter.
"I'm a pretty strong person and I broke down and cried for at least 30 minutes".
Officials said the truck driver from Thursday's collision is expected to recover.
An investigative team from the National Transportation Safety Board was reportedly en route to the scene. It happened along Interstate 40 in New Mexico, near the Arizona border. State police say 49 people were on board the bus at the time.
Several described seeing passengers on the ground, screaming and crying.
