PADANG, Indonesia (Reuters) -- Rescue teams were struggling to find scores of people trapped under debris and survivors pleaded for aid after a powerful quake hit the Indonesian city of Padang, possibly killing thousands.
The 7.6-magnitude quake struck the bustling port city of 900,000 people on September 30, toppling hundreds of buildings. Telephone connections were patchy, making it hard for officials to work out the extent of destruction and loss of life.
"I have been through quakes here before and this was the worst. There is blood everywhere, people with their limbs cut off. We saw buildings collapsed, people dying," said American Greg Hunt, 38, who was at Padang airport.
A Reuters reporter in the city said rescuers were pulling people from buildings, but there was little sign of much aid being distributed yet. Fuel was also in short supply and there was a report of looting.
Health Minister Siti Fadillah Supari told reporters at an airport in Jakarta before leaving for Padang that the number of dead could be numbered in the thousands, given the widespread damage. A worker compiling disaster data at the social ministry put the number killed of confirmed deaths at 529.

A woman clutching her dead baby cried for help: "My son is dead. My son is dead." TV footage showed troops carrying a woman on a stretcher, blood seeping from wounds on her legs and her body covered in dust.

Damage to roads had affected transport of rubber in West Sumatra, the fifth-largest producing province for rubber in Indonesia.
