Drone sightings have disrupted flights at Singapore’s main airport for the second time in a week, authorities have said.
About 18 arrivals and departures were delayed and seven flights diverted at Changi airport late on Tuesday “due to bad weather and unauthorised drone activities”, Singapore’s civil aviation authority said.
The disruption lasted about an hour, it said.
Changi, one of Asia’s busiest hubs, closed one of its runways last week for short periods due to unauthorised drone flying, disrupting dozens of flights.
It is against the law in Singapore to fly a drone within 5km (three miles) of an airport without a permit.
Drones are increasingly disrupting flights at airports around the world. London’s Gatwick was paralysed for 36 hours in December following repeated drone sightings, with tens of thousands of passengers affected.
