Relatives of a Frenchman on death row in Indonesia for drug offences begged President Francois Hollande and the European Union to save him after his appeal was rejected by the Supreme Court on Tuesday.

"Our family calls on President Francois Hollande and the European Union to do everything possible to save Serge Atlaoui from the firing squad," his brother Andre told AFP, describing his "dismay" and "lack of understanding" at the court's decision.
