Several flights to and from Bali have been cancelled after the Mount Lewotobi Laki-laki volcano began spewing ash as high as 9km in the sky.

Eighty-three international routes were cancelled on Wednesday, the general manager of Bali's international airport said in a statement, after Mount Lewotobi Laki-Laki spewed a 9km tower of ash into the sky. The volcano has erupted more than a dozen times over the last two weeks, killing at least nine people and forcing the evacuation of thousands.

Several international airlines have resumed flights to and from Indonesia's resort island of Bali, an official said on Thursday, after multiple eruptions of the Mount Lewotobi Laki-laki volcano belched ash up to 10 km (16 miles) into the air.
