Colombia severs diplomatic relations with Iran

Colombia formally severed diplomatic relations with the Islamic Republic of Iran on September 19, 2026, and designated the Islamic Revolutionary Guard Corps as a terrorist group, according to the outlet AlbertoNews. The decision responds to national and hemispheric security concerns, which the Colombian government links to activities by terrorist groups and human rights violations by the Iranian state.

The diplomatic rupture affects bilateral political ties, although the consular channel will be maintained in accordance with the Vienna conventions of 1961 and 1963, according to the information published by the news portal.

The Colombian government adopted this measure after considering international precedents that include restrictions in the Strait of Hormuz and obstruction of the verification work of the International Atomic Energy Agency (IAEA) on Iran's nuclear program.

Following this decision, the Colombian executive announced a tightening of border and security controls to prevent people associated with Iran's Islamic Revolutionary Guard Corps from entering the country.
