Â Church groups will join with Amnesty International this Sunday for a mass demonstration outside Downing Street against torture. The multi faith group Peace & Justice in east London, which has been collecting signatures on a petition against the use of torture evidence in UK trials, called on people of all faiths to come out and protest. "It is vital that it is made clear to government that the use of torture in any form cannot be condoned. Our most basic human rights are at stake here," said a spokesperson for Peace and Justice in east London. "The UK government is seeking agreements to return people to countries known to use torture. Agreements have been signed with Jordan and Libya and are being sought with Algeria and other countries. They are not work the paper they are written on," said a spokesperson for AI. "The law is clear. States must never torture people and must never send people to countries where they might be tortured." Meanwhile, AI and Reprieve have called on the US government to stop blocking United Nations access to its Guantánamo detention centre and agree to access to all prisoners. The organisations were responding to the passing of a midnight deadline for the US government to agree to terms for a visit to Guantánamo by five independent experts of the United Nations Commission on Human Rights.
