46 people, thought to be migrants, have been found dead in the back of a lorry in Texas near the Mexico border.

16 others, including 4 children, have been taken to hospital.

Authorities say they're suffering from heat stroke - there wasn't any air conditioning or water in the trailer.

Three people have been arrested.

Bill McManus, San Antonio's police chief, says they were alerted by a city worker.
