At least 30 people were killed when a strong earthquake and tsunami hit the city of Palu on Indonesia’s Sulawesi island on Friday, a hospital official told Metro TV in a report broadcast on Saturday. A tsunami up to two metres (six feet) high swept through Palu at dusk after the sleepy but growing tourist resort was rocked by a 7.5 magnitude earthquake. Amateur footage shown by local TV stations, which could not immediately be authenticated by Reuters, showed waters crashing into houses along Palu’s shoreline, scattering shipping containers and flooding into a mosque in the city.
