No fewer than 46 migrants have been discovered dead in and around a large trailer truck that was abandoned on the roadside on the outskirts of the Texas city of San Antonio.
The grim discovery was one of the worst disasters involving migrants in the United States in recent years — and came five years after a similar deadly incident in the same central Texas city, a few hours from the Mexican border.
‘At this time we have processed approximately 46 bodies that have been triaged and tagged and declared deceased,’ San Antonio Fire Chief Charles Hood told reporters.
He went on to reveal that about 16 people had been transported to the hospital alive and conscious — 12 adults and four children.
There were no initial details on the age or nationalities of the deceased.

‘The patients that we saw were hot to the touch, they were suffering from heat stroke, heat exhaustion, no signs of water in the vehicle, it was a refrigerated tractor-trailer but there was no visible working A/C unit on that rig,’ Hood said.
Officials have confirmed that about three people so far been arrseed over the incident.
‘Tonight we are dealing with a horrific human tragedy,’ San Antonio Mayor Ron Nirenberg told a press conference.
‘So I would urge you all to think compassionately and pray for the deceased, the ailing, the families,’ he said.
‘And we hope that those responsible for putting these people in such inhumane conditions are prosecuted to the fullest extent of the law.’
San Antonio, which lies about 250 kilometers (150 miles) from the border, is a major transit route for people smugglers.
It has also been gripped by a record-breaking recent heat wave, and temperatures in the area hit 103 degrees Fahrenheit (39.5 degrees Celsius) on Monday.
The vehicle was found on a road near Highway I-35, a major US artery that stretches all the way to the border with Mexico.
A large-scale emergency operation was underway at the scene involving police, firefighters and ambulances.
In a statement, the DHS said it had initiated an investigation after receiving the call from San Antonio police “regarding an alleged human smuggling event”.
Dozens of emergency responders who had worked at the scene underwent a stress debriefing following the operation.
