A Mexican air force cargo plane crashed at Monterrey International Airport on Wednesday, killing five military personnel, Mexico's national security agency said.
Spokesman Alejandro Poire said the exact circumstances of the accident were not yet clear. Milenio television reported that the plane crashed after the crew attempted an emergency landing shortly after taking off from the airport.
Milenio identified the five victims as the plane's pilot and co-pilot, navigator, electrician and mechanic.
The Central-North Airport Group, the regional airport authority, identified the plane as an Antonov AN32.
A statement from the authority said flights in and out of the airport were continuing.
Monterrey, Mexico's third-largest city, is located in the northeastern Mexican state of Nuevo Leon.
The airport is about 140 miles south of Laredo, Texas.
