At least 10 Cuban migrants hiding in a cargo truck have died after the vehicle overturned on a highway in the southern Mexican state of Chiapas.
The accident happened near the Guatemalan border, AFP reported, citing local security officials.
At least 17 others were injured, local officials said, adding that one of the victims was a child. One report said they were all female.
This was the second fatal accident in less than a week involving migrants.
The driver of the truck, which is not designed to carry so many people, fled the scene of the accident, the National Migration Institute (INM) said in a statement.
