Extremist tape condemns Spanish
The video was found in the rubble of a Madrid apartment where seven suspects in the bombings blew themselves up on April 3.
The Arabic-language tape was badly damaged in the explosion. In the video, three of the suicide attackers claimed responsibility for the March 11 attacks in the name of a group linked to al-Qaida and threatened more bloodshed unless Spain withdraws from Iraq and Afghanistan in a week.
