The officials say that Muhsin al-Fadhli is dead. He was a leader of the Khorasan Group, a cadre of al-Qaida operatives who were sent from Pakistan to Syria to plot attacks on the West. Officials say the Khorasan Group is embedded in the al-Nusra front, Syria's al-Qaida affiliate.
The officials spoke on condition of anonymity because they weren't authorized to discuss the operation.
