At least 75 people are dead and thousands are trapped under rubble after a strong earthquake shook the Indonesian island of Sumatra. The US Geological Survey said the epicentre of the 7.9 quake struck at 1716 local time was about 50 kilometres off the coast, near the city of Padang. There are reports of widespread destruction to buildings and bridges. Rustam Pakaya, head of the health ministry's crisis centre, said a hospital was among the collapsed buildings. Local media reported the roof of the city's airport had also collapsed. Witnesses said residents ran out of buildings in Padang – which has a population of 900,000 – and surrounding cities. Indonesian geophysics and meteorology agency said a number of hotels in Padang have been destroyed. Reports said the shaking could be felt in high buildings in the capital, Jakarta, and was also felt in Singapore and Malaysia.<br/>
