On August 23, Israeli Mossad reportedly gave his name to the CIA as part of a list of 19 names they said were planning an attack in the near future. Only four of the names are known for certain – Narwaf, Atta, al-Shehhi and al-Mihdhar, but again, the connection was not made with previous contacts by local law enforcement.[40] On the same day, he was added to an INS watch list, together with Mihdhar to prevent entry into the US.
