Spanish police have arrested at least seven people suspected of financing Islamic terrorism, news reports said Friday. The arrests began Thursday night in the Costa del Sol region of southern Spain, the news agencies Efe and Europa Press reported. The detainees were suspected of raising money for an Algerian-based Islamic extremist organization, the Salafist Group for Call and Combat, the news agencies reported. Efe said they were arrested on orders from the National Court, the Madrid-based tribunal that oversees probes of terrorism cases in Spain. Interior Ministry officials were not immediately available to comment on the reports.
