More than 380 people have been confirmed dead after a tsunami triggered by a magnitude 7.5 earthquake hit an Indonesian city on Friday.
Video on social media shows people screaming and fleeing in panic and a mosque among the buildings damaged.
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.
A less powerful quake earlier on Friday had killed at least one person and injured at least 10 in the smaller fishing town of Donggala.
