Human rights, religious and anti-death penalty groups are calling on the US state of Texas to stop the execution of a man who may be brain-damaged. Since 1976 the USA has executed 1,188 people. There are 3,300 still on death row.
In the aftermath of the World Day Against the Death Penalty on 10 October, Amnesty International has highlighted several cases of people facing execution - including one in the USA being distorted by religious fundamentalism.
Amid pressure from both sides, the governor of Texas has blocked part of a bill which would have prevented the death penalty being used for a particular category of people convicted under a provision called the Law of Parties.
Worldwide vigils have been held for Troy Davis, a death row prisoner in Georgia, USA, who is believed to be innocent, and is still trying to get a court to hear evidence collected since his original trial 18 years ago, which could prove his innocence.
