Colombian President Gustavo Petro agrees to receive undocumented migrants as President Donald Trump steps up deportation efforts. Mr. Petro initially rejected two groups of migrants sent to Colombia because they were not treated with “dignity.

US President Donald Trump announced sweeping tariffs on Colombia before abruptly pulling the threat after reaching a deal on the return of deported migrants, a move that rattled global markets in the space of several hours.

Colombia said Monday it had sent aircraft to repatriate migrants deported from the United States after apparently bowing to President Donald Trump's threats of painful tariffs for defying his plans for mass expulsions.
