Authorities have detained seven undocumented Syrians in southeastern Mexico before they were able to take a flight to the capital, federal police said Tuesday.
The migrants were stopped at the Tapachula airport in Chiapas state, near the border with Guatemala, along with a Mexican man accused of human trafficking.
The Mexican man told authorities that the group, ages 21 to 31, had visas but "inconsistencies" were found in their passports when they tried to purchase tickets to Mexico City, the federal police said in a statement, which did not say when the detention took place.
Officials say some 140,000 foreigners enter Mexico illegally every year, many through Guatemala, on their way to the United States.
The majority are from Central America but a number also come from Asia and Africa.
