The Spanish Prime Minister, Jose Luis Rodriguez Zapatero has called for the US to provide "correct and adequate information" over the claims that the CIA secretly used European airports to transport suspects to third countries for interrogation.

Zapatero told reporters "These are very serious allegations. The British have asked for explanations from the American administration and we will listen to these explanations, but we want correct and adequate information."

The CIA is also said to have set up secret jails within European countries where terrorist suspects are interrogated beyond the reach of anti-torture legislation which would hinder such interrogations inside the USA.
