Five airports in Indonesia have been shut, including those in the tourist hotspot Bali, because of a volcanic eruption, transport officials say.
Mount Raung in East Java has been spewing ash into the air for nearly a week, raising concerns it could interfere with aircraft safety.
A spokesperson for state airport operator Angkasa Pura said Indonesian that Denpasar would be closed until at least 21:30 local time (13:30 GMT).
However, Indonesian transport ministry official JA Barata said the re-opening of the airports would be based on the activity on Mount Raung, which is about 120km from Denpasar airport.
The four other affected airports are the International Airport in Lombok, Selaparang Airport also in Lombok, Blimbingsari Airport in Banyuwangi, East Java and Notohadinegoro Airport in Jember, East Java.
Scores of flights have been postponed indefinitely or cancelled by airlines, including Jetstar and Virgin Australia who have halted all flights in and out of Denpasar Airport.
