A strong tsunami triggered by a magnitude 7.5 earthquake has hit a coastal Indonesian city, officials say.
Waves of up to 2m (6.6ft) high swept through Palu on Sulawesi island, not long after authorities had lifted a tsunami warning.
Video on social media shows people screaming and fleeing in panic and a mosque amongst the buildings damaged.
Officials have reported five deaths – but it is not clear if those were as a result of the tsunami.
Last month, a series of earthquakes struck the Indonesian island of Lombok, killing hundreds of people – the biggest on 5 August killed more than 460.-BBC
