The nations spent much of the day in a tense standoff, with the U.S. president threatening tariffs and visa restrictions after Colombia turned away two deportation flights.

Colombia's Foreign Affairs Ministry said the government was sending a Colombian Air Force plane to San Diego to pick up a group of Colombians who were on a deportation flight that was not allowed to land on Sunday morning.

The country’s leader, Gustavo Petro, backed down after a clash with President Trump, which started when Mr. Petro turned back U.S. military planes carrying deportees.
