Indonesia tsunami: Aftershocks rock Palu day after disaster

Strong aftershocks have continued to hit the Indonesian island of Sulawesi, where a major quake and tsunami killed at least 408 people and injured 500, reports BBC. 

Dozens remain missing, some thought to be trapped in the debris of collapsed buildings in the city of Palu.

Bodies have been lying in city streets and the injured are being treated in tents because of damage to hospitals.

An air traffic controller at Palu airport died ensuring a plane took off safely after Friday's quake.

The scale of casualties and damage beyond the city is still unclear.

Anxious survivors in Palu bedded down in the open air on Saturday night, heeding advice by officials not to return to their homes as a precaution. Some buildings were completely flattened.

Indonesia is prone to earthquakes because it lies on the Ring of Fire - the line of frequent quakes and volcanic eruptions that circles virtually the entire Pacific Rim.

In 2004, a tsunami triggered by an earthquake off the Indonesian island of Sumatra killed 226,000 people across the Indian Ocean, including more than 120,000 in Indonesia.
