46 migrants found dead in US

At least 46 migrants were found dead in the back of a truck in the southern US state of Texas on Monday, officials confirmed.

The sweltering semi-trailer was discovered on the outskirts of San Antonio, around 160 miles (250 kilometers) from the US southern border with Mexico.

"We're not supposed to open up a truck and see stacks of bodies in there," the city's fire chief Charles Hood said.

Meanwhile, San Antonio police chief William McManus said it was the largest incident of its kind in the city.
