The US Department of State has updated its global travel advisory, placing 23 countries under its highest warning level (Level 4: Do Not Travel) due to severe security risks and limited consular assistance.The list includes nations like Afghanistan, Belarus, and parts of Nigeria such as Borno, Jigawa, and Yobe states.The advisory warns against travel to these areas because of crime, terrorism, kidnapping, and civil unrest.

Nigeria's government has rejected the assessment, claiming it reflects Washington's internal risk evaluation rather than an overall security analysis.The update follows previous advisories that kept Nigeria under Level 3: Reconsider Travel.

The State Department urges Americans to avoid the listed regions, emphasizing the dangers posed by local conditions and restricted government support.This advisory highlights ongoing global security concerns and the US's approach to travel safety.
