British holidaymakers have been warned not to visit eight countries as they have been declared “too dangerous”.

The Foreign Commonwealth and Development Office (FCDO) added eight new countries to its ‘do not visit’ list and issued an urgent warning to holidaymakers, reports Shropshire Star.

In total, 66 countries – or parts of countries – have been declared “too dangerous” for British tourists by the FCDO.

Eight nations added to the list by FCDO are Russia, Ukraine, Iran, Sudan, Lebanon, Israel, Belarus and the Palestinian territories.

These nations are categorised as either on the “red list” or “black list” by experts in the UK Foreign Office.

Though the FCDO has not banned UK citizens from travelling to these countries, it said that the tourists might find themselves without any Government support if something were to go wrong.

The advice given for each country is slightly different but the same warning is given that help may not be offered to those who travel.

The Belarus warning from the FCDO reads: “Russian military operations are taking place in Belarus.

“There is some risk that direct conflict linked to the war in Ukraine may spread to Belarus. If conflict starts, FCDO’s ability to offer consular assistance will be severely limited. Routes out of the country are limited, particularly by air.”

Currently, the Foreign Office is sternly advising against travel, or all but essential travel, to 24 destinations on the ‘black list’.

These destinations are: Afghanistan, Belarus, Burkina Faso, Central African Republic, Chad, Haiti, Iran, Iraq, Israel, Lebanon, Libya, Mali, Niger, North Korea, Palestinian territories, Russia, Somalia, Somaliland, South Sudan, Sudan, Syria, Ukraine, Venezuela, and Yemen.
