Migration flows surged following Joe Biden's rise to power.
A group of 98 migrants were rescued from a truck bound for the United States, but abandoned by his driver on the side of a road in eastern Mexico, barely a month after 53 people died in similar conditions in San Antonio, Texas.
The migrants were found overnight from Wednesday to Thursday on a road in the state of Veracruz, according to a police source.
They said they were abandoned by the driver, according to the police report which does not specify the nationality of those found.
In addition to the 98 people rescued, a hundred escaped, according to witnesses quoted by the press.
A dozen people had to be hospitalized with bruises and problems with lack of oxygen. Others got out of the vehicle with backpacks, an AFP correspondent noted.
The tractor-trailer was traveling up the Gulf of Mexico highway toward Nuevo Laredo, on the border with the United States and Texas.
On June 27, 56 migrants were found asphyxiated in an abandoned trailer near San Antonio.
On December 9, 56 migrants also died in a truck accident on a Chiapas highway in southern Mexico. On Wednesday in Nicaragua, 16 migrants were killed and 47 injured in a bus accident.
In Chiapas these days, hundreds of migrants blocked a road facing the offices of the Migration Institute to demand temporary resident permits allowing them to cross Mexico into the United States.
Since 2014, some 6,430 migrants have died or disappeared in Mexico on the way to the United States, according to the International Organization for Migration (IOM).
