Al-Qaida Plot to Bomb Plane foiled by CIA

The CIA foiled a plot by al-Qaida's affiliate in Yemen to bomb a U.S.-bound airliner this month, senior U.S. officials told NBC News.
Officials said the plot involved a bomb that improved on the one that had been sewn into the underpants of Umar Farouk Abdulmutallab, who failed in a plot to blow up a Detroit-bound airliner on Christmas Day 2009. That device did not detonate.
