11 African countries among 23 nations under highest US travel warning: Full list

The United States Department of State has placed 23 countries under its highest travel advisory, urging American citizens to avoid travelling to the listed destinations due to severe security risks.

The latest advisory, published on the State Department's official X (formerly Twitter) account on Wednesday, July 15, 2026, classifies the affected countries as Level 4: Do Not Travel — the highest warning in the department's four-level travel advisory system.

According to the State Department, a Level 4 advisory is issued when a country faces extreme security threats or when the US government's ability to provide emergency consular assistance to its citizens is significantly limited.

Several of these countries continue to grapple with armed conflicts, terrorism, political instability and military coups, creating serious security concerns for travellers.

The Sahel region—particularly Burkina Faso, Mali and Niger—has experienced a significant deterioration in security in recent years as extremist groups continue to expand their operations across the region.

A number of the countries on the Level 4 advisory are also among those affected by travel restrictions introduced by the administration of President Donald Trump as part of broader immigration and national security measures.
