Madrid:
Three alleged Al Qaeda suspects with possible plans for an attack in Spain or elsewhere in Europe have arrived at Spain's National Court for questioning by a judge.
Police with automatic weapons closed streets as the suspects arrived in a police van. The judge was expected to decide on Friday after the closed-door hearing if they will remain detained.
A Russian, a Russian of Chechen descent and a Turk were arrested on Wednesday. The Turk was arrested in the southern city of La Linea bordering the British colony of Gibraltar. The Russians were picked up traveling by bus toward the French border.
Authorities say enough explosive material was found in the La Linea house where the Turk lived to blow up a bus. Authorities found evidence suggesting they were experimenting with ultralight planes.
