Spanish authorities arrested him in 2002 on charges that he was a chief financier for al-Qaeda in Spain.

He is also alleged to have been a planner in the bombing of two US embassies in Kenya and Tanzania in 1998.

Brahim is married to a Finnish national identified as Pirjo.

Spanish counter-terrorism judge Baltasar Garzón has also alleged that Ahmed Brahim had "routine contacts" with Swiss-born Islamic scholar Tariq Ramadan in 1999.
