It was an innocuous email, one of millions sent every day by spouses with updates on the situation at home. But this one was of particular interest to the National Security Agency, and contained clues that put the sender’s husband in the cross hairs of a CIA drone.
Days later, Hassan Ghul — an associate of Osama bin Laden who provided a critical piece of intelligence that helped the CIA find the al-Qaida leader — was killed by a drone strike in Pakistan’s tribal belt.
The U.S. government has never publicly acknowledged killing Ghul. But documents provided to The Washington Post by former NSA contractor Edward Snowden confirm his demise in October 2012 and reveal the agency’s extensive involvement in the targeted killing program that has served as a centerpiece of President Barack Obama’s counterterrorism strategy.
