MAPUTO, Mozambique — More than 60 undocumented migrants believed to be Ethiopians were found dead in a cargo truck in northwestern Mozambique on Tuesday.

The truck, which had entered Mozambique from the neighboring country of Malawi, was stopped at a checkpoint in Moatize, near the Zambezi River in Tete Province, according to the online site Zitamar News.

According to the authorities, the driver was ordered to open the truck when officials heard bashing noises coming from the container, and 14 survivors were also found inside. The victims were said to have died from a lack of oxygen.

The survivors will be screened for the coronavirus and put into quarantine, health officials told Zitamar.
