Flights were disrupted at a major airport in the US yesterday after reports of drone sightings.
Authorities briefly halted arrivals at Newark Liberty Airport in New Jersey following the reports of drone activity near the airport.
US media reports that the sightings happened at the private Teterboro Airport - around 25km from Newark - but flights at the larger airport were suspended as a precaution.
Operations resumed shortly after, although flights were operating with delays of almost an hour in the wake of the incident.
In a brief statement, the airport said: "We’re coordinating with the [Federal Aviation Authority] & fully supporting all federal law enforcement authorities as they investigate this incident."
Newark is the 11th busiest airport in the US, and the second largest airport serving the New York area.
Yesterday's disruption in the US comes in the wake of several drone-related incidents in the UK over the past month.
There was widespread disruption at Gatwick Airport less than a week before Christmas after multiple reports of drone sightings.
The sightings led to all flights at the airport being suspended for an entire day.
Earlier this month, flights were briefly suspended at London's Heathrow Airport after a possible drone sighting.
Officials here met earlier this month to discuss the recent disruption in the UK, with Transport Minister Shane Ross pledging to take any "appropriate action" necessary to help address any future illegal drone activity.
