Flights at Zurich airport were disrupted on Monday after a technical fault in air traffic control systems, triggered by the establishment of a no-fly zone for peace talks between the United States and Iran.
The security measures, implemented to protect the diplomatic negotiations taking place in Switzerland, caused operational issues that affected scheduled air traffic.
The incident underscores the complex logistical challenges involved in securing high-level diplomatic engagements in major European hubs.
The talks, which focus on de-escalation efforts in the region, come amid heightened tensions.
Previous reports indicated that negotiations had been interrupted following statements by US President Donald Trump, adding uncertainty to the diplomatic process.
The disruption at Zurich airport serves as a reminder of the broader impact geopolitical events can have on commercial aviation.
