Sinabung volcano has erupted on the Indonesian island of Sumatra, engulfing villages in ash and killing at least 14 people.
Mount Sinabung spewed hot gas, ash and rocks 1.5 miles into the air in a series of eruptions during the morning.
Emergency official Sutopo Purwo Nugroho said three schoolchildren and a teacher were among the dead.

Thousands of people were evacuated in September when Sinabung erupted after being dormant for three years. Many were allowed back to their homes on Friday.
Officials fear there may have been more casualties, but they cannot get closer because of the heat from the eruption.
Pictures taken at the scene showed rescue workers recovering bodies that were buried in ash.
When Sinabung volcano erupted in 2010, at least two people were killed and 30,000 others were displaced. Before 2010, Sinabung had not erupted in 400 years.

Indonesia has raised the alert for the Mount Sinabung volcano in North Sumatra to the highest level.
The status was raised from “stand-by” to “caution” – the highest alert for volcanic activity – on Sunday.
People have also been warned to stay at least 3 miles from the crater.
Mount Sinabung has been showing signs of life since September, after being dormant for three years. Over the weekend, it shot ash and rocks far into the air, prompting the alert move.
More than 15,000 villagers in the area had already been moved to temporary shelters, disaster management officials said in a statement.

Airlines have also been advised not to fly near the area.
The disaster management agency said they had changed the alert level because they anticipated there would “more eruptions and because the intensity of eruptions has been increasing”.
A local official told Agence-France Presse agency that “loud thunderous sound and vibrations” accompanied the eruptions.
No casualties have been reported so far.
When the volcano last erupted in 2010, at least two people were killed and 30,000 others were displaced.
Before 2010, Mount Sinabung had not erupted in 400 years. It is one of around 130 active volcanoes in the country.
