At least 46 migrants have been found dead inside a tractor-trailer vehicle in San Antonio, Texas. Another 16 people - including four children - who needed medical attention were taken to nearby hospitals, San Antonio Fire Chief Charles Hood told reporters. "We're not supposed to open up a truck and see stacks of bodies in there," he said. Hood said he was hopeful that all 16 people taken to hospital would survive. All of them were hot to the touch and appeared to be suffering from heat stroke. There were no signs of water or working air conditioning in the truck. Local media reported the truck was involved in a suspected human smuggling incident. San Antonio is about 240km from the border with Mexico.
