Colombia Cuts Diplomatic Ties With Iran Over National Security Concerns

Colombia has officially severed diplomatic relations with Iran, citing national and hemispheric security concerns and what its government describes as deteriorating trust between the two countries. Colombia’s Ministry of Foreign Affairs announced the decision on September 24, saying the diplomatic break had taken effect on September 19, 2026.

According to the Colombian government, the decision was based on its foreign-policy priorities surrounding national security, hemispheric security and the fight against transnational crime.

Bogotá also cited alleged links between the Iranian government and international terrorist and narcoterrorist groups, as well as human-rights violations attributed to Iranian authorities. The Colombian government additionally pointed to attacks against countries outside the Middle East conflict, the reported blocking of the Strait of Hormuz and what it described as obstruction of International Atomic Energy Agency efforts to assess Iran’s nuclear programme.

Despite the announcement, Colombia has made clear that the decision does not amount to a complete break in all relations with Iran.

The Colombian Foreign Ministry said consular relations will remain in place under the relevant provisions of the Vienna conventions. This means the two countries can continue certain consular functions even though formal diplomatic relations have been severed.

The diplomatic relationship between Colombia and Iran dates back to 1975. Both countries maintained diplomatic contacts over the years and reached agreements covering areas including culture and consular affairs.

Iran has rejected Colombia’s allegations. Iran’s Foreign Ministry described the accusations as baseless and condemned Bogotá’s decision to sever diplomatic relations, arguing that the move was contrary to mutual respect and the interests of the two countries.

The dispute therefore involves competing claims: Colombia says its decision is driven by security and foreign-policy concerns, while Iran rejects the accusations used to justify the move.The diplomatic rupture comes as Colombia’s new government under President Abelardo de la Espriella makes significant changes to the country’s foreign-policy direction.

The administration has moved toward closer relations with the United States and has also taken steps to restore diplomatic ties with Israel, following the previous government’s decision to sever those relations in 2024.

Colombia also announced on September 24 that it had designated Iran’s Islamic Revolutionary Guard Corps as a terrorist organization, citing security concerns and the organization’s activities beyond Iran’s borders. For now, the diplomatic break marks a significant change in Colombia-Iran relations. While formal diplomatic ties have ended, consular relations remain, leaving a limited channel between the two countries.

The move also reflects the broader realignment of Colombia’s foreign policy under its new administration as Bogotá reassesses its relationships with Iran, Israel and the United States.
