Indonesian authorities have raised the alert level for Mount Ibu, a volcano in North Maluku province, to the highest level following a series of eruptions.

The 1,325-metre (4,347ft) volcano on the north-west coast of the remote island of Halmahera has been spewing thick grey ash and dark clouds up to 5,000m (16,400ft) into the air every day since last Friday.
