More than 250 leading doctors have called on the US to end the practice of force feeding prisoners at its detention camp at Guantanamo Bay.
Some 500 prisoners are still being kept in the US base in Cuba.
In an open letter published in the British medical journal The Lancet, the doctors say prisoners have the right to refuse treatment, including feeding.
The doctors come from seven countries, including Ireland.
They say medical personnel involved should be disciplined by their professional bodies.
The US has argued that the Geneva Convention does not apply to prisoners at the camp. It says the prisoners are enemy combatants.
