Mount Sinabung, in Indonesia's North Sumatra province, has begun erupting again, sending an ash cloud 2.5km (1.9 miles) into the sky.

Sinabung has erupted sporadically since 2010 after lying dormant for 400 years. Earlier this year, a major eruption killed 15 people and forced hundreds to flee their homes. This week's increased activity is raising fears of another deadly eruption.
