Spanish police arrested 131 suspected terrorists in 2004, the Interior Ministry said Thursday. Nearly half of the arrests were in connection with the Madrid train bombings. Another 42 people were arrested as part of an investigation into a cell that allegedly plotted to blow up the National Court, the nerve center of Spain's anti-terror investigations, said the ministry statement reviewing its work in 2004. Interior Minister Jose Antonio Alonso said on Wednesday that Spain remains on high alert against radical terrorism, especially the armed Basque separatist group ETA.
