Federal Council authorises deployment of up to 2 000 troops and a temporary no-fly zone for Bürgenstock summit

The Swiss Federal Council has formally approved a request from canton Nidwalden to call in as many as 2 000 members of the Swiss Armed Forces to support civil authorities during the 19 June meeting between high-level US and Iranian delegations at the Bürgenstock resort. The decision, announced in Bern on 17 June, underscores the event’s elevated security profile and Switzerland’s obligations under international-protection law. Military personnel will assist cantonal police with perimeter protection, aerial surveillance, logistics and rapid medical response. Armoured infantry companies are being positioned to secure approach roads, while air-defence units will backstop the Federal Office of Civil Aviation’s (FOCA) 46-kilometre air-space restriction that takes effect at 06:00 on Thursday, 18 June. The army’s Joint Operations Command has placed helicopters and Super Puma transport assets on alert at nearby Alpnach air base. Under article 67 of the Swiss Military Act, such “subsidiary assistance” deployments require Federal Council sign-off when troop levels exceed 2 000 or when the mission lasts longer than three weeks. While the authorised window is limited to 18–20 June, officials indicated that soldiers could remain on standby for subsequent high-level diplomacy linked to the Gulf cease-fire. The air-space closure mirrors procedures used during the 2024 Ukraine peace summit but is broader this time because flight paths into Zurich and Basel airports intersect the protected cylinder. Business-aviation operators have already filed for reroutes via Austrian and Italian corridors, incurring extra fuel and slot costs. Cross-border commuters on Lake Lucerne ferries must also expect ID checks by mixed military-police patrols.



In light of these heightened entry checks, travellers who still need to confirm their visa status can streamline the process through VisaHQ, whose Swiss portal (https://www.visahq.com/switzerland/) centralises requirements, electronic forms, and expedited courier options. The platform’s live support proves especially valuable when last-minute itinerary changes arise around security events like the Bürgenstock talks.

For companies organising board meetings, roadshows or client events in central Switzerland, the Federal Council’s order effectively locks in a long security weekend. Travel managers should verify shuttle-bus permits with the military liaison office, advise visitors to carry passports rather than driver’s licences, and update insurance providers about elevated force-majeure risk until the air-space embargo lifts on 20 June.
