Russia, Belarus, Ukraine, Iran, Sudan, Lebanon and Mozambique, along with the French overseas territories of Mayotte and New Caledonia, represent the nine newest additions to the UK Foreign Office (FCDO)’s travel red list, where trips to the entire country are deemed perilous, reports The Telegraph.

This red list now numbers 25 destinations, representing 31,766,973 square kilometers—or 21.3 percent of the world’s landmass.

A further 47 countries are partially out of bounds.

The security situation has improved in two countries. Back in 2019, Burundi and Mauritania were also entirely off-limits. But now most of Burundi is deemed safe to visit, as is a significant chunk of Mauritania, including its coastal areas and capital, Nouakchott.

Ukraine, Russia and its close ally Belarus were added to the travel red list in February 2022. Israel, Lebanon and Palestine were added in October 2023, though parts of Israel and Palestine are now rated safe.

Iran, which appeared on the brink of a tourism renaissance a few years ago (British Airways even resumed direct flights from Heathrow to Tehran), has been entirely off-limits since late 2019.

The FCDO advised against all travel to Sudan following the onset of armed clashes between rival military factions in 2023.

Mozambique has been on the no-go list since December 2024 due to widespread unrest following a disputed election.

The nine new additions represent around 16 percent of the world’s landmass.

The risk level has risen elsewhere. Mexico, a burgeoning winter-sun favorite, continues to face serious problems with violent crime, and the FCDO now advises against all but essential travel to large swathes of the country, including most of the states of Chihuahua, Sinaloa, Zacatecas, Colima, Guerrero and Michoacán, as well as the border city of Tijuana.

Tanzania, previously rated entirely safe, now has no-go zones: namely its border with the Cabo Delgado province of Mozambique, “due to attacks by groups linked with Islamic extremism.”

Moldova, previously problem-free, now has a danger zone: Transnistria, as do Peru (the Chapare region of Cochabamba Department), Ghana (the Bawku Municipal area), Guatemala (areas close to its border with Mexico) and Uganda (including Queen Elizabeth National Park). And escalating gang violence has seen Ecuador’s no-go areas swell, with seven coastal regions (Esmeraldas, Manabí, Santa Elena, Guayas, El Oro, Los Ríos and Santo Domingo de los Tsachilas) now deemed unsafe.
