Eight Chinese migrants have been found dead on the coast of southern Mexico, authorities said, after their boat capsized along a popular but perilous route for illegally entering the United States.

The bodies of the seven women and one man were discovered Friday on a beach in San Francisco del Mar, Oaxaca, the state’s prosecutor’s office said in a statement.

Treacherous boat rides up the coast of Mexico are often used by migrants hoping to cross into the US in an attempt to bypass checkpoints on closely monitored land routes.
