Footage shows several trucks with police markings on them arriving at the jail. About 20 men then walked into that jail without any resistance from guards.

Almost a dozen of them are suspected members of the Zetas - the armed wing of the powerful Gulf drug cartel - with involvement in kidnapping or robberies.

Interpol has put out an international security alert for 11 of the fugitives.

Prison guards told local media that they had been threatened by the Zetas in recent months.
