A series of volcanic eruptions of Mount Lewotobi Laki Laki on Indonesia's remote island of Flores killed nine people and injured dozens with searing lava and ash, as buildings crumbled and terrified residents ran for their lives in darkness.

The Indonesian government plans to permanently relocate thousands of residents after a series of volcanic eruptions at Mount Lewotobi Laki-laki killed nine people and damaged thousands of houses.

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.
