JAKARTA (Reuters) -Mount Lewotobi Laki-laki in Indonesia's East Nusa Tenggara province erupted on Tuesday, spewing a towering ash cloud 11 kilometres (6.8 miles) high, the country's volcanology agency said.

The eruption of Mount Lewotobi Laki-laki has affected 87 international and domestic flights at I Gusti Ngurah Rai Airport in Bali.

Indonesia’s Geology Agency said in a statement it recorded the volcano unleashing 10,000 meters (about 32,800 feet) of thick grey clouds on Tuesday afternoon, following significant volcanic activities, including 50 in two hours, rather than the usual daily 8 to 10 activities.
