A volcanic eruption in Indonesia sent an enormous ash cloud more than six miles into the sky, disrupting or canceling dozens of flights to and from the tourist island of Bali.

Mount Lewotobi Laki Laki’s eruption prompted evacuations and flight cancellations to and from Bali and other destinations.

Mount Lewotobi Laki-Laki on the island of Flores spewed an ash tower more than 11km (6.8mi) into the sky on Tuesday, the country's volcanology agency said. There have not been any reports of casualties. Authorities have raised the highest alert level and advised residents to avoid activities within a 7km radius around the crater.
