Brazil's government says that a young Brazilian hiker who had plunged hundreds of meters from the ridge of a towering Indonesian volcano and was trapped there for almost four days has been found dead.

Officials said rescuers found Juliana Marins dead and would evacuate her body on Wednesday morning because of bad weather.

The family of a Brazilian hiker found dead in Indonesia days after a fall climbing a volcano have criticised the rescue effort as too slow, before authorities carry out an autopsy Thursday to find out the time of her death.
