The FCDO widened its Saudi Arabia travel advice on the evening of Sunday 20 September. Its change note reads: "The Foreign, Commonwealth and Development Office (FCDO) advice against all but essential travel extends to include the cities of Abha and Khamis Mushait in Aseer province."
The rest of the note is continuity. The FCDO continues to advise against all travel to within 10km of the border with Yemen, and against all but essential travel to areas between 10km and 80km from it. What is new is that Abha and Khamis Mushait, both in Aseer province, now sit inside the all but essential advice.
The background is on the FCDO's regional risks page: "In 2026, direct military conflict between the Houthi rebel military group and the Governments of Yemen and Saudi Arabia has resumed." It goes on: "Since 13 July 2026, the Houthis have launched missiles and drones targeting several cities, airports, military bases and energy infrastructure sites across Saudi Arabia including Abha, Jizan, Najran, Riyadh, Taif, Jeddah and Yanbu as well as Saudi shipping vessels in the Red Sea." It adds that some civilians have been injured and that there is a risk of more attacks and escalation.
The UN picture from last week points the same way. At the Security Council on 15 September, Assistant Secretary-General Khaled Khiari warned that "The ongoing escalation is not limited to the Bab al-Mandab Strait and Yemen". The UN's account of that meeting records reported casualties and damaged homes in several Saudi cities after Houthi missile and drone strikes on 14 September. The UK's published statement for the same meeting says overnight Houthi attacks "have reportedly injured a further 13 civilians, damaged homes and residential areas, and disrupted commercial aviation."
One limit, stated plainly. We cannot point you to a primary source for a specific incident behind the 20 September change, and the FCDO note gives no trigger. We are not going to assert one.
For anyone with work in Aseer, four things follow.
Insurance first. The FCDO states: "Your travel insurance could be invalidated if you travel against advice from the Foreign, Commonwealth & Development Office (FCDO)." An existing Saudi policy should not be assumed to cover Abha or Khamis Mushait now. Get cover confirmed in writing before anyone travels.
Shelter and warnings. The FCDO's guidance is that "The greatest risk is from falling debris caused by intercepts, and you are safest inside a secure structure". It also notes that Saudi Civil Defence issues early warning alerts to people in affected areas. Both belong in the arrival brief, together with the nearest secure structure at each accommodation and venue.
Airports. "The authorities can temporarily close airports near the Saudi Arabia-Yemen border. Check with your airline before travelling to airports near the border." Plan a road alternate and build in hold time rather than treating a flight into the south-west as fixed.
Behaviour. The FCDO asks travellers to "refrain from capturing or sharing images of conflict-related incidents" and to "stay away from areas around oil infrastructure and military facilities". For principals who post on social media, that is a conversation to have before arrival, not after an intercept overhead.
A last point on reading the advice itself. The FCDO's pages do not fully agree with each other today. The warnings and insurance page lists the cities attacked without Taif, which the regional risks page includes, and the air travel section of the safety and security page still describes a 2022 attack as the last incident at Abha International Airport. Treat the regional risks page as the current statement.
