U.S. President Donald Trump announced on Sunday the imposition of “urgent retaliatory measures” in response to Colombia’s decision to block U.S. military aircraft carrying deported migrants.

Trump stated that “Colombian President Gustavo Petro issued this order, putting U.S. national security at risk.”

The measures include a 25% emergency tariff on all goods entering the United States, a travel ban on Colombian officials, and increased customs inspections.
