Counterterrorism expert Rohan Gunaratna will later claim in a book that al-Qaeda planned to bomb a target inside the US this year. Operatives plan to get explosives in Italy and ship them to the US via Cuba. However, the operation is aborted. Further details, such as what the target is or who is involved, are unknown. Gunaratna is known to have sources inside US intelligence and will claim the information came from the CIA, but it is unclear when the CIA may have first learned about this alleged plot.
