More than 30 international flights to and from the island were cancelled or diverted after ash belched from East Java's Mount Bromo and drifted into airspace over Bali on Thursday.Thousands of foreign tourists, mostly from Australia, were stranded, airlines said.
The airlines which cancelled flights included Australian companies Jetstar and Virgin Blue, along with Cathay Pacific, KLM, Singapore Airlines, China Airlines, Korean Air and Qatar Airways.Mount Bromo began rumbling in November and the government had raised the eruption threat warning to the maximum red alert before lowering it last month.
Indonesia's most active volcano, Mount Merapi in central Java, has killed more than 350 people in a series of violent eruptions which started in late October.
