More than 280 people are dead after tsunami waves of up to 10 feet crashed into several towns along Indonesia’s coast, crushing buildings and dragging people into the sea.
The tsunami arrived without warning, caused by a landslide when the Anak Krakatau volcano erupted.
Rescuers are trawling through towns and beaches, searching for survivors, while the death toll is expected to keep rising.
More than 1,000 people are injured, and many are waiting in temporary shelters and hospitals.
The Medecins Sans Frontiers is assisting on the ground.
