Brits have been warned that the Foreign Office is advised against “all but essential travel” to 21 countries. Venturing to these parts of the world could prove risky, according to the Foreign, Commonwealth and Development Office (FCDO).

This warning affects entire countries or parts of countries in Europe, Africa, Asia and South America.

As reported by The Independent, of the 226 countries or territories with FCDO travel advice, 73 have alerts in place. Of these, 21 countries have “all but essential travel” warnings.

The other 52 have complete “do not travel” advisories. These cautions come due to security issues, health risks and legal differences with the UK.
