Mahmoud Jaballah is an Islamic Jihad operative living in Canada and being closely monitored by Canadian intelligence (see May 11, 1996-August 2001). On April 1997, Islamic Jihad top leader (and al-Qaeda number two leader) Ayman al-Zawahiri contacts Jaballah, and the phone call is monitored by Canadian intelligence, which later mentions that Jaballah tells al-Zawahiri about his status in Canada. In February 1998, Jaballah is given al-Zawahiri’s satellite phone number. Canadian intelligence later claims the number is “subsequently contacted many times by Jaballah.” [Canadian Security Intelligence Service, 2/22/2008 ] Presumably Canadian intelligence begins monitoring al-Zawahiri’s phone number by this time, but details about what they do, how long they are able to monitor the number, and how much they learn remain unknown.
