Volcano erupts after 400 dormant years

21,000 people have been evacuated from their homes after a volcano erupted for the first time in 400 years

An Indonesian volcano has erupted, causing panic in villages and delays to flights to the immediate area.

Mount Sinabung, in the north of Sumatra island, started emitting lava and ash early on Sunday, followed by another eruption on Monday, sending plumes of ash two kilometres into the air.

So far about 21,000 people have been evacuated from the area and are living in temporary accommodation.

The volcano had previously been dormant for 400 years.
