Mexico and Guatemala say they have rescued at least 104 people from captivity and arrested 14 of their alleged human traffickers.
Police in Guatemala said they raided two houses near the Mexican border and found at least 60 people who wanted to travel to the United States illegally.
They arrested eight alleged smugglers.
In Mexico, the authorities said they found 44 Guatemalan migrants in a house near the Guatemalan border and arrested six alleged human traffickers.
Migrants from Central America often pay smugglers to enter the US illegally, but are frequently abused by their traffickers.
They can hold migrants in captivity to extort more money from the victims’ relatives.
