Nairobi, Nov. 24 -- On Monday, June 17, 2013, the East African Express flight 803 lumbered across the Mogadishu runway as it prepared to take off to Nairobi's Jomo Kenyatta International Airport via the sun-baked Wajir International Airport. It had 532 passengers - and one was a terrorist.

Inside the Wajir airport, and even in Mogadishu's Aden Adde International Airport, nobody seemed to notice the innocent-looking 20-year-old Mohamed Abdinur Said, passenger no. 3 in the flight manifest, wearing a light-olive green shirt, as he went through the regular security protocols.

Actually, there was nothing unusual about him: His brand new passport, number P00278810, issued a week earlier, indicated he was a student with no history of travel.
