JAKARTA (Reuters) - Seven people have died and two are in critical condition after Mount Sinabung on Sumatra island erupted on Saturday, said an Indonesian disaster agency official, adding that the army and police are still searching for survivors in the area.

The 2,460-metre (8,070 foot) tall volcano is among the country's most active. When Sinabung erupted in 2014, more than a dozen people were killed and thousands were evacuated. Before recent times, its last known eruption was four centuries ago.
