Flights at Zurich Airport experienced disruptions Sunday due to a technical issue with air traffic control. The problem stemmed from the implementation of a no-fly zone over Buergenstock, Switzerland, where U.S.-Iran peace negotiations were underway. Integrating the restricted airspace into radar systems caused a glitch, according to Skyguide, the Swiss air traffic control authority. The disruption impacted flight schedules, though the issue was subsequently resolved. Authorities confirmed the technical fault was directly linked to security protocols for the ongoing talks. No further details regarding the extent of the flight delays were immediately available. The incident highlights the logistical complexities of hosting sensitive international negotiations.
