IRAQI security forces have captured a Tunisian al-Qa’ida militant allegedly behind the February bombing of a revered Shia shrine that unleashed a massive wave of sectarian violence.
Abu Qudama al-Tunisi, allegedly a member of a cell that destroyed the Golden Mosque at Samarra, was captured when he and about 15 foreign fighters tried to attack an Iraqi army checkpoint in Dhuluiyah, north of Baghdad.
The 15 foreigners were killed in a firefight with Iraqi forces.
