June warnings include Iran, Syria and Russia, with serious insurance, evacuation and border risks for UK travellers.

UK travellers are being urged to check FCDO warnings before booking or flying, as destinations including Iran, Syria and Russia carry do-not-travel advice.
UK travellers are being urged to check official safety advice before travelling abroad after warnings remained in place for a number of high-risk destinations on 2026-06-29. Countries highlighted include Iran, Syria and Russia, where the Foreign, Commonwealth and Development Office warns that travel can expose visitors to serious security, detention, conflict and consular-access risks. The key point for travellers is that FCDO advice is not just a suggestion: it can affect whether your insurance pays out, whether your travel company can operate the trip, and how much help the UK government can realistically provide in an emergency.
The FCDO issues different levels of travel advice depending on the risk in a country or region. The strongest warnings usually advise against all travel, while another category advises against all but essential travel. These advisories may apply to an entire country or to specific areas such as border zones, conflict regions, military areas, disputed territories or provinces with a heightened risk of terrorism, kidnapping or civil unrest. Travellers should read the full country page carefully rather than relying only on a headline summary, because the difference between a nationwide warning and a regional warning can be crucial.
The countries specifically highlighted in the latest coverage on 2026-06-29 include Iran, Syria and Russia. These are destinations where UK travellers may face unusually severe risks, including conflict-related disruption, arbitrary detention, limited consular support, terrorism, sudden border closures or restrictions on movement. In some cases, flights may be limited, payment cards may not work reliably, and travellers may find it difficult to leave quickly if the security situation deteriorates. Because the official list can change without much notice, the FCDO’s live country pages should be treated as the final authority before booking or travelling.
The most immediate practical issue is travel insurance. Many policies exclude cover if you travel to a destination where the FCDO advises against all travel or against all but essential travel, unless you have specialist cover agreed in advance. That means claims for medical care, evacuation, cancellation, theft or disruption may be refused if they are linked to travel against official advice. If you are booking a flight, hotel, tour or visa for a high-risk country, get written confirmation from your insurer before paying any non-refundable costs.
If you have already booked travel to a destination affected by FCDO advice, your first step should be to check whether the warning applies to your exact destination and route. Contact your airline, tour operator, accommodation provider and insurer to ask what options are available, including rerouting, postponement, credit, refund or cancellation. Package holiday travellers may have stronger protections if the trip can no longer be delivered safely, while independent travellers may need to negotiate separately with each supplier. Keep screenshots and written records of the FCDO advice in force at the time you make decisions, as this may help with insurance or supplier discussions.
Travellers already in a country covered by severe FCDO advice should prioritise safety over sightseeing or onward plans. Monitor the FCDO country page, local authorities, trusted news sources and your airline’s operational updates, especially if airports, borders or roads could close with little warning. Keep essential documents, medication, cash, power banks and communications equipment accessible in case you need to move quickly. If commercial departure routes are still available, consider leaving earlier rather than waiting for the situation to worsen.
Dual nationals and people visiting family can face additional complications in countries with strained diplomatic relations or internal security concerns. Some governments do not recognise dual nationality, which can limit the UK government’s ability to provide consular support if a traveller is detained or prevented from leaving. Family visits can also involve travel to smaller towns, rural areas or border regions where risks may be higher than in major cities. Before travelling, dual nationals should read the nationality and consular-support sections of the FCDO page especially carefully and consider whether the trip is essential.
Travellers planning overland routes need to pay particular attention to regional warnings rather than only country names. A route that looks straightforward on a map may cross areas affected by conflict, terrorism, mines, criminal checkpoints, closed borders or military restrictions. This is especially important for backpackers, motorcycle travellers, expedition groups and people using long-distance buses or trains across multiple countries. Always check each border crossing separately and have a realistic alternative route that avoids areas where the FCDO advises against travel.
FCDO advice does not automatically mean every flight will be cancelled, and airlines may continue operating to some destinations even where travel warnings exist. If an airline cancels your flight, you may be entitled to a refund or rerouting under applicable passenger rights rules, depending on the route and circumstances. However, if the flight still operates and you decide not to travel because of FCDO advice, your refund options may depend on the fare rules, airline flexibility policy, travel insurance and whether you booked as part of a package. Contact the airline before missing the flight, because failing to show up can sometimes cancel onward or return sectors.
The safest approach is to treat FCDO advice as an essential pre-travel check, not a last-minute formality. Look up the official country page before booking, again before paying final balances, and once more shortly before departure. If a warning is in place, do not assume that previous experience, family connections or local contacts remove the risk. For most leisure travellers, choosing a lower-risk alternative destination will be simpler, safer and far less costly than trying to travel against official advice.
