A sports utility vehicle carrying 10 children veered out of control and overturned on its way to a water park in East Texas on Monday, killing five of the young people, according to local reports.

Four girls aged two, three, six and 13, and a boy aged five were dead on the scene, about 70 miles east of Dallas, the Star-Telegram reported.  A three-year-old died late on Monday night, according to The Dallas Morning News.

Five children and two adults were taken to hospitals in Dallas and Tyler after the crash at around 2:15 p.m. (3:15 p.m. ET), NBC News affiliate in Dallas reported.

Four children were listed in critical condition, the Dallas Morning News reported.

The Texas Department of Public Safety said the vehicle, a GMC Envoy, was carrying two adults and 10 children when it rolled into a ditch, the paper reported.  The SUV did not have any child seats or enough safety belts, it added.

Nine occupants were ejected when the vehicle rolled into a ditch, according to The Dallas Morning News.

Officials said it wasn’t clear what had caused the the single-vehicle crash.

“There’s a language barrier between investigators and the occupants,” Trooper Jean Dark told the newspaper.

Everyone in the car was wearing a swimsuit, Dark added, which led investigators to conclude that the group was heading to a water park.
