Papua New Guinea's national airline, Air Niugini, has indefinitely suspended all flights into one of the country's busiest airports, Tokua.
Flights to Tokua airport were suspended due to increased volcanic emissions in the East New Britain township.
The airline's flight information office says the airport's runway is heavily covered in ash.
A spokesperson for the airline said that the air space over Tokua airport is being monitored and any decision to resume flights will depend on the prevailing winds dispersing volcanic emission away from the aerodrome.
