Mexico launches probe into migrant killings

MEXICO CITY (AP) — Mexico's National Human Rights Commission says it is launching an investigation into the deaths of four migrants attacked by an armed gang aboard a freight train in southern Mexico.

The commission says the attackers started demanding $100 per migrant, saying those who refused would be thrown from the train.

The National Immigration Institute confirmed that four people died. It said three Mexicans were also wounded.

The Institute said the six assailants carried four pistols and a machete.

The commission said Friday the attack occurred Wednesday in the southern state of Oaxaca.

In March, two Central American migrants died in a similar attack. Migrants frequently hop freight trains to reach the United States.
