Support for Guantanamo detainee Omar Deghayes is spreading across the globe.

There are now campaigners lobbying to secure justice for the 36-year-old law graduate from Saltdean in countries including Spain, France, Belgium, Iraq and the United States.

Peace activists including American Judy Linehan, the mother of an American soldier in Iraq and a spokeswoman for US organisation Military Families Speak Out, and Paresh Kathrani, a human rights lawyer who lives in Paris and has been on the board of Amnesty International for seven years, have offered support.

Wes Hamilton, an ex-Vietnam soldier and member of large US organisation Veterans for Peace, is to lobby US senators to put pressure on the administration to accord Mr Deghayes a proper legal process. Lieven de Cauter, a Belgian lawyer and philosopher in the World Tribunal in Iraq, has pledged to help with legal advice.

The Peace Movement Belgium is holding regular demonstrations outside the US embassy at the European Parliament.

Activists in Spain are to lobby their Government to demand the extradition of Mr Deghayes to their country. This option was recently mooted by the Home Office because he was alleged to have appeared in a terrorist training video that featured as evidence in a trial there, though facial recognition experts dismissed it as a case of mistaken identity.

Dozens of delegates pledged their support for the campaign at an international conference for human rights at the European parliament last month.

Mr Deghaye's brother Abubaker and local Save Omar campaigners Jackie Chase and Thomas King spoke at the conference and visited the US ambassador with Green Party MEP Caroline Lucas.

Mrs Chase, 48, of Grantham Road, Brighton, said: "It was just wonderful.

"We had people from across the world coming to us and telling us they would do whatever we wanted, anything they could do to help."

The conference was organised by the Bertrand Russell Peace Foundation. The foundation's chairman Ken Coates also pledged his support.
