What is the main task for aid workers now?

In Iran, more than 28,000 bodies have been recovered from the earthquake-stricken city of Bam. And officials say the death toll could now reach 50,000. Tens of thousands of people have been left bereaved and homeless. And search and rescue efforts are now turning to humanitarian work. Aid workers are pleading for more clothing, blankets and medicine. From the air, the devastation to the ancient city of Bam is evident. On the ground, trucks are carrying much-needed supplies into the city. Bulldozers are clearing the rubble. And those who survived last Friday’s pre-dawn quake are doing what they can to help.
