Troopers said the crash happened at mile marker 394 at approximately 3:40 p.m. Thursday.

A preliminary investigation revealed that a semi-truck and another car collided for unknown reasons  while traveling northbound on I-75 and hit a guardrail.

"After the collision, both vehicles traveled through the guardrail, in the center median and into the southbound lanes," troopers stated in a press release.

The semi-truck then collided with a van and another semi-truck in the southbound lanes, causing the van to overturn and eject some of the occupants.

Both semi-trucks caught fire, FHP said.

The five Louisiana children killed were inside the van and were headed to Disney World, according to the FHP.

Both semi-truck drivers were killed. They were both men.

At least seven others were injured in the crash. Troopers are working to confirm with hospital staff if there are any more injuries.
