US Issues Highest Travel Warning for 23 Countries, Including 11 in Africa.

The United States Department of State has issued its highest Level 4 travel advisory for 23 countries, urging American citizens not to travel to those destinations because of serious security risks.

The advisory, announced on July 15, 2026, warns that the listed countries face threats such as armed conflict, terrorism, political instability, violent crime, or limited access to U.S. consular assistance. A Level 4 advisory represents the highest warning in the State Department's four-tier travel advisory system.

African countries on the Level 4 advisory list:

Burkina Faso

Central African Republic

Chad

Democratic Republic of the Congo

Libya

Mali

Niger

Somalia

South Sudan

Sudan

Uganda

According to the U.S. State Department, several of these countries continue to experience insecurity linked to armed conflicts, extremist violence, military coups, and political unrest. The Sahel region, particularly Burkina Faso, Mali, and Niger, has seen worsening security conditions in recent years.

Other countries under the Level 4 advisory:

Afghanistan

Belarus

Myanmar (Burma)

Haiti

Iran

Iraq

Lebanon

North Korea

Russia

Syria

Ukraine

Yemen

The State Department also noted that some of the countries on the advisory list are subject to additional U.S. travel restrictions introduced under the administration of President Donald Trump as part of broader immigration and national security measures.

U.S. authorities said travel advisories are reviewed regularly and may change based on evolving security conditions, political developments, crime levels, health risks, and the availability of consular services. Travelers are advised to check the latest travel guidance before making international travel plans.
