Since being convicted as an Al-Qaeda bomb plotter last year, Sakka has decided to reveal his alleged role in some of the key plots of recent years, providing a potential insight into the unanswered questions surrounding them. His story is also one of a globetrotting terrorist in an organisation that is truly multinational.
He is an enigma and, despite his involvement in three terrorist outrages involving British citizens, he is virtually unknown in this country.
By his own account he is a senior Al-Qaeda operative who was at the forefront of the insurgency in Iraq, took part in the beheading of Briton Kenneth Bigley and helped train the 9/11 bombers. He has been jailed in connection with the bombing of the British consulate in Istanbul.
