The United Nations' humanitarian chief said Thursday the powerful earthquakes that struck Indonesia have killed at least 1,100 people. John Holmes said the latest figures “suggest the death toll has risen already to 1,100” and that there are “many hundreds of injured people as well” because of Wednesday's 7.6-magnitude earthquake, which originated in the sea off Sumatra island. It was followed by another earthquake Thursday morning. Holmes said he feared thousands more were trapped in the rubble of homes, hotels, hospitals and schools destroyed or badly damaged.
