No-fly zone for Iran talks disrupted flights at Zurich airport, authorities say

VIENNA - A technical fault in air traffic control, triggered by security measures for peace talks between the US and Iran in Switzerland, caused disruptions at Zurich airport on June 21, the aviation authorities said, adding the problem had been resolved.

The glitch occurred following the integration of a restricted zone over Buergenstock, the Swiss mountain resort where negotiations are taking place, into radar display systems, Swiss air traffic control authority Skyguide said.

The zone was only decided at the last minute because the decision to hold the latest round of talks was not finalised until June 20, according to a statement.

Operations have since returned to normal, Skyguide said, adding: “The systems are running smoothly, and security was ensured at all times.”

By midday, 12 arrivals and 14 departures had been cancelled, an airport spokesperson told Reuters. At least 60 departures were delayed, she added.

US Vice-President J.D. Vance arrived for peace talks with Iran at Buergenstock on June 21 as foreseen in a tentative peace deal, but the diplomacy was overshadowed by Iran’s announcement that it had reimposed its blockade of the Strait of Hormuz.

Switzerland has promised a “discreet and reliable setting” for the talks at the resort, located just over 50km south of Zurich airport as the crow flies. REUTERS
