The Swiss government has decided to impose airspace restrictions during the one-day visit of Pope Francis later this month.
The Federal Council made the decision on Friday following a request from the cantonal authorities in Geneva.
The restriction concerns small aircraft – namely passenger aircraft and helicopters – in the Geneva region. It will be active from 9 am to 9 pm on June 21.
Commercial flights to and from Geneva International Airport are not affected.
The Swiss army is allocating a maximum of 200 military personnel to reinforce the air police service, in addition to setting up a logistics and health support service for the visit.
Pope Francis is expected to meet the Swiss president in Geneva and hold a mass at the airport.
The last papal visit to Switzerland was in 2004, when Pope John Paul II came to Bern.
