Military officials says Mexican soldiers have rescued 47 suspected kidnap victims during a drug trafficking investigation.
Authorities say the 44 Guatemalan migrants and three Mexicans were found locked in a house in Reynosa on Tuesday.
Officials say no arrests have been made in connection with the apparent kidnappings.
Mexican officials have not publicly commented on who might be responsible for the kidnappings.
Last August, 72 migrants from Central and South American were found slain on a ranch in Mexico.
Mexican officials say the Zetas drug cartel was responsible for those killings.
