A second unauthorised drone flying in a week has halted operations at Singapore's Changi Airport.
It's been stated by Singapore's Civil Aviation Authority (CAAS) that 18 flights had been delayed, and seven flights diverted due to drones and bad weather.
Last week, one runway was suspended at Changi delaying 37 departures and arrivals, including one flight which was diverted to Kuala Lumpur.
In a statement CAAS said that "15 departures and three arrivals were delayed and seven flights were diverted due to bad weather and unauthorised drone activities".
The statement continued: "Members of the public are reminded that the authorities take a serious view of errant operations of unmanned aircraft which may pose threats to aviation or endanger the personal safety of others".
Investigations are ongoing.
Drone disruptions have become a major problem at airports, as evidenced by the issue which happened at London Gatwick airport.
Drones or unmanned aircraft systems in Singapore are not allowed within 5km of any airport or military airbase and must fly lower than 200 feet. They also must not weigh heavier than 7kg.
