some call him the marlborough man. others just call him one eye. cbs reporter david martin says no matter what his alias, the u.s. calls him our newest enemy. >> reporter: maktar, aka one eye, because he lost an eye fighting in afghanistan, aka the marlborough man because he made a living smuggling cigarettes. no westerner knows him better than robert fowler, who was his hostage in 2008. >> it was absolutely no doubt who was the boss. he wasn't a flashy guy. but he was rather soft-spoken. but as soon as he began speaking, everybody would listen. >> reporter: though he has been known to intelligence agencies as the leader of the north african affiliate of al-qaeda. >> they would tell me repeatedly, we fight to die, while you fight to go home to your wives and kids. how can we possibly lose? they believed their fight was god's fight and because it was god's fight, it would be won. >> reporter: in 1994, they hijacked an airline, with a plan to blow it up over the eiffel tower. they later took the name al- qaeda, in an effort to attract more recruits.
