At least 54 people are dead and dozens more injured after a lorry carrying people thought to be migrants destined for the US crashed in southern Mexico.
Video footage of the incident – one of the worst accidents to involve migrants risking their lives to reach America – showed the vehicle overturning as it hit a bend in the city of Tuxtla Gutierrez.
The crash occurred on a highway leading toward the Chiapas state capital.
More than 100 migrants found
The Attorney General’s office put the death toll at 54, which included a number of women and children. More than 100 people were travelling inside the trailer, authorities said.
Dozens were injured and taken to hospitals across Chiapas, a state which borders Guatemala.
The victims appeared to be immigrants from Central America, though their nationalities had not yet been confirmed.
Luis Manuel Moreno, the head of the Chiapas state civil defence office, said some of the survivors said they were from the neighbouring country of Guatemala.
“The trailer couldn’t handle the weight of people,” a witness said.
“It took a bend, and because of the weight of us people inside, we all went with it.”
Images from the scene showed injured people splayed out on the ground and rows of what appeared to be bodies.
President Andres Manuel Lopez Obrador described the tragedy as “very painful”.
It was one of the worst single-day death tolls for migrants in Mexico since the 2010 massacre of 72 migrants by the Zetas drug cartel in the northern state of Tamaulipas.
Migrant caravans heading for America
Migrants fleeing poverty and violence in Central America typically trek through Mexico to reach the US border.
However, some opt to travel in lorries organised by smugglers in extremely dangerous conditions.
Last month officials found 600 people hidden in the back of two lorries in eastern Mexico.
Record numbers of people have been arrested on the US-Mexico border this year as migrants seek to capitalise on President Joe Biden’s pledge to pursue more humane immigration policies than his hardline predecessor, Donald Trump.
