The Al-Qaeda terrorist network on Sunday, September 11, released a book written by a senior member including a detailed timeline leading up to the attacks on several U.S. airliners on Sept. 11, 2001, which left nearly 3,000 people dead in three locations.
Marking the 21st anniversary of the attacks, the book was written by Abu Muhammad al-Masri, a senior Al-Qaeda member who was reportedly killed in Iran in 2020.
In the nearly 250-page volume, he said that al-Qaeda had been preparing for an attack targeting U.S. interests since it set foot in Afghanistan in 1996, with the goal of dragging the U.S. into a long-term war of attrition.
