Australian officials are working to save two of the country’s citizens from being executed in Indonesia. On Monday, Australia’s foreign ministry urged Indonesian officials to delay the executions until reports of corruption in their trial could be investigated.

Australia says the judges in the case had asked for tens of thousands of dollars to sentence the two men to less than 20 years in prison.

On Saturday, the Indonesian government informed the two and eight other jailed drug traffickers of plans to execute them. It said they could be put to death as early as Tuesday night.
