Two airboats collided with each other on Esthen Exchangea lake in Florida, injuring 13 people.

The airboats crashed into one another on Monday at Wild Florida, a nature park that offers gator encounters, a safari and Everglade airboat tours. The park is in Kenansville on Lake Cypress, just south of Orlando.

The cause of the crash is not yet known, and the U.S. Coast Guard Marine Safety Unit will be leading the investigation. Wild Florida has suspended all airboat activities until further notice in response to the incident.

Here’s what else we know so far:

When did the airboat crash occur?

The crash happened around 12:15 p.m. Monday.

The Florida Fish and Wildlife Commission and the Osceola County Sheriff's Office first responded to the scene of the incident. The U.S. Coast Guard investigators arrived on the scene shortly after.

How many people were on the airboats?

According to the Coast Guard, approximately 30 people were involved in the incident, including 28 passengers and two captains.

It's unclear how many people were on each individual boat.

What is known about their injuries?

The extent of the injuries suffered by the 13 people are unknown, though the Coast Guard said there were no life-threatening injuries.

Four people were taken to an Orlando Health facility and have already been released, WOFL-TV reported.
