Donald Trump's plan for mass deportations of migrants from the United States is facing initial obstacles. Colombia is the latest country to refuse to accept planes carrying deportees. Previously, Mexico did not permit a US military aircraft to land on its territory.

Colombian President Gustavo Petro said Sunday the country would reject U.S. military flights carrying deported migrants.

Colombia on Sunday turned away two US military aircraft with migrants being deported as part of President Donald Trump's immigration crackdown, a US official said, in at least the second case of a Latin American nation refusing US military deportation flights.

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

U.S. President Donald Trump said on Sunday he would impose retaliatory measures on Colombia including tariffs, sanctions and travel bans after the South American country turned away two U.S. military aircraft with migrants being deported as part of Trump's immigration crackdown.

President Donald Trump said he is slapping an emergency 25 percent tariff on all goods imported from Colombia on Sunday after the country’s president turned away two U.S. military aircraft full of detained Colombian migrants.

Colombia will reject deportation flights from the United States after Brazil decried the treatment of migrants arriving handcuffed and shackled, complicating President Donald Trump’s plans and providing a contrast with the cooperative acceptance of Mexico and Guatemala.

Mexico, Colombia and Brazil are all pushing back on Trump's deportation of migrants in handcuffs or on military planes.

Many remain determined to reach the U.S. through more dangerous means, riding freight trains, hiring smugglers and dodging authorities.
