The United States Department of State has placed 23 countries on its highest-risk travel advisory, Level 4, urging Americans to avoid all travel to these destinations for any reason.

In an updated advisory sighted on Saturday from the country’s TravelGov X handle, the department stated that Level 4 is assigned to countries where local conditions are considered dangerous or where the US government’s ability to assist its citizens is limited.

“We issue Travel Advisories with Levels 1–4. Level 4 means DO NOT TRAVEL. We assign Level 4 based on local conditions and/or our limited ability to help Americans there,” the department said in the notice posted on Thursday.

It added, “These places are dangerous. Do not go for ANY reason.”
