Indonesia has confirmed it will execute 14 people on death row for drug crimes in the coming days.

UN human rights officials have expressed concern over the planned executions, urging Jakarta to put an end to “unjust” capital punishment.

The inmates have not been officially named but they are known to include citizens of Nigeria, Zimbabwe, Pakistan and India.

They will be executed at Nusakambangan prison island.

The prisoners have been notified of the plans for their executions, in accordance with Indonesian law, and could be put to death as early as Friday.

Attorney General Muhammad Prasetyo said the 14 had been put in isolation. The executions are due to take place by Sunday at the latest.
