Huge ash clouds thrown up by an Indonesian volcano have forced airlines to cancel all flights to and from the northern Australian city of Darwin, BBC reports.
Mount Sangeang Api began erupting on Friday and plumes of ash have been sweeping south towards Australia.
Qantas, Jetstar and Virgin Australia have all cancelled flights. Services between Australia and the province of Bali have also been hit.
The authorities say other airports could be affected in the coming days.
“The volcano is undergoing a sustained, rather significant eruption at the moment,” Emile Jansons, manager of the Darwin Volcanic Ash Advisory Centre told Reuters news agency.
“Nobody has a very good handle on what this volcano is likely to do in the next 24 hours or beyond,” he said.
