Indonesia's attorney general's office has notified nine foreigners and an Indonesian convicted of drug trafficking that their executions will be carried out within days.

Spokesman Tony Spontana says the ten convicts were moved to isolation cells on Saturday and given a 72-hour execution notice. It indicates they will face the firing squad at the earliest on Tuesday or Wednesday.

The executions will take place in Besi prison on Nusakambangan Island.

The foreigners are four Nigerian men, two Australian men, a Filipino woman, and one man each from Brazil and France.

However, the French man Serge Atlaoui is still awaiting a legal appeal over the procedure in his request for clemency.

The planned executions have triggered an international outcry, but Indonesia insists the punishment is part of the country's "drugs emergency."
