At least five people are dead and several others hurt as a 4WD carrying more than a dozen people crashed while fleeing from Border Patrol agents in South Texas.
Dimmit County Sheriff Marion Boyd says the SUV went out of control at more than 160km/h and overturned on Texas Highway 85, ejecting those inside.
Texas Department of Public Safety officials say four were pronounced dead at the scene. A fifth person died at a hospital.
Most of the occupants were believed to be living in the country without legal permission.
Boyd told San Antonio television station WOAI a driver and one passenger are believed to be US citizens. Both are in custody.
Some injured were taken by helicopter to San Antonio, about 145km northeast.
