The terrorist organization Tehrik-i-Taliban Pakistan planned a terror attack in the city of Barcelona, which was stopped a few days before they intended to perform it. They intended to conduct a suicide bombing on the Barcelona Metro. The metro plot was intended to become the first of a series attacks in Spain, Germany, France, Portugal and the United Kingdom as those countries contributed to the International Security Assistance Force in Afghanistan, with the timing determined by al Qaeda making political demands through Taliban leader Baitullah Mehsud.
