May 10 (Reuters) - Six bodies were found on Sunday ‌in a train boxcar ‌in Laredo, Texas, according to police.

A Union ​Pacific worker discovered them in a train yard at a remote location near the Mexican border, and ‌police and firefighters ⁠later confirmed they had died, said Laredo Police Investigator ⁠Joe Baeza.

Police have not determined how they died, Baeza said. The ​investigation is ​ongoing, he ​said.

There were no ‌survivors, he said.

Police did not say where the individuals were from.

Past instances of multiple deaths in trains and tractor trailers not far ‌from the U.S.-Mexico border ​have involved migrants, ​including a ​2022 incident in which ‌53 were found dead ​in an ​abandoned truck with malfunctioning air conditioning on the outskirts of ​San Antonio.
