MADRID (AFP) - A judge in Spain Friday remanded in custody three of seven people arrested in an operation against a gang suspected of forging passports for Al-Qaeda-linked groups, court sources said. The seven six Pakistanis and a Nigerian were held in raids in Barcelona on Tuesday night. Three others - two Pakistanis and a Thai woman - were held in Thailand as part of the same Operation Kampai. The judge in Madrids National Court, which handles terrorism cases, ordered Junaid Humayun and Atiqur Rehman, both Pakistanis , and Nigerian Babatunde Agunbiade held without bail on suspicion of collaborating or belonging to a terrorist organisation, the sources said. Another Pakistani, Jabran Asghar, was freed on 13,000 dollars bail, three others were released on condition they do not leave Spain and appear at a police station every two weeks, and one, Mohammad Saddique Khan Begum, was freed unconditionally. The interior ministry also said Friday that Spanish and Thai investigators have found new evidence of links to Sri Lankas defeated Tamil Tiger rebels. Spanish police experts have travelled to Thailand and are working with Thailands Department of Special Investigations to analyse the numerous documents seized from the cell, the interior ministry said Friday. An initial examination of photographs seized has turned up evidence of the membership of some members of the terrorist organisation the Liberation Tigers of Tamil Eelam. Many of its members were based in Western countries, where they obtained financial assistance for the organisation through extortion and drug trafficking, it said.
