More than 400 people have been confirmed dead after a tsunami triggered by a magnitude 7.5 earthquake hit an Indonesian city on Friday.
Waves up to 3m (10ft) high swept through Palu on Sulawesi island.
Video on social media shows people screaming and fleeing in panic and a mosque among the buildings damaged.
Strong aftershocks rocked the city on Saturday. Thousands of homes have collapsed, along with hospitals, hotels and a shopping centre.
Rescue efforts are under way, though hampered by a major power cut. The main road to Palu has been blocked due to a landslide, and a key bridge is out of action.
