An eruption of Indonesia's Lewotobi Laki-laki volcano spewed ash clouds more than 8 kilometres (5 miles) high, authorities said as they raised the alert status to the highest level, and an Australian airline cancelled some flights into Bali on Friday.

The Mount Lewotobi Laki Laki volcano in south-central Indonesia erupted three times into Friday, sending an ash column 8,000 meters (26,000 feet) high and prompting authorities to expand the danger zone around the volcano.

A volcano on Flores Island in Indonesia woke up island residents early Friday when the latest eruptive episode sent ash and smoke up 8,200 feet into the air, according to local geological officials.
