FT.com / UK - Yemeni threat pushed up US agenda: "The risk posed by al-Qaeda in Yemen has long been of concern to western intelligence services. In 2000 Yemeni suicide bombers killed 17 people when they struck the USS Cole. The US waged a largely successful counter-terrorism campaign over the next three years, using unmanned drones to kill key operatives. But in the past three years AQAP has been thriving again in eastern Yemen, amid the ravages of its civil war.
Today western intelligence chiefs believe the risk posed by Yemeni jihadism has become especially serious."
