BBC News with Iain Purdon

Three days after a tsunami struck the remote Mentawai island chain in western Indonesia, the full scale of the disaster is emerging. Rescue teams have reached most of the worst-affected areas to find homes and offices destroyed, swathes of land under water and swollen bodies strewn across roads and beaches. Karishma Vaswani reports.

The district chief of the Mentawai Islands told the BBC that the focus for rescue teams now is to treat the hundreds of people who've been severely injured in the tsunami. He added that most of the villages affected have now been reached. Mass graves have been dug for the large number of people who were killed, and thousands of refugees who lost their homes in the disaster have been moved into temporary shelters. The local government says it plans to set up a rehabilitation and reconstruction programme for Mentawai.
