Colombia has denied entry to two U.S. military deportation flights, according to officials from the Department of Homeland Security and the Defense Department.

Colombia banned U.S. flights of deported migrants as the Trump administration said it has begun his promise to conduct the “largest deportation operation” in U.S. history—one of the first signs Trump’s plan could face pushback from migrants’ home countries.

Several Latin American leaders have reluctantly accepted some migrant flights in recent days.

Colombian President Gustavo Petro said Sunday he would block US deportation flights until migrants were guaranteed "dignified treatment," escalating a row between Washington and left-wing Latin American governments over US President Donald Trump's migrant crackdown.

Brazil’s foreign ministry said late on Saturday that it would demand explanations from the US government over the ”degrading treatment” of Brazilians on a deportation flight, while Mexico on Friday also refused such a flight to land in the country.
