Alaska volcano erupts again

The Mount Redoubt volcano in the US state of Alaska has erupted for the sixth time in 24 hours, spewing ash and steam 15 kilometres or 9.3 miles into the air.



The volcano, located south-west of the state\'s biggest city, Anchorage, began erupting late on Sunday after a 20-year lull.



Ash has reportedly fallen on towns north of Anchorage, but the city itself has not been affected by the eruption.



Alaskan Airlines has cancelled a number of flights because of the ash.



Officials at the Alaska Volcano Observatory were able to monitor the latest eruption live via a webcam.
