Top al-Qaeda bomb maker in Yemen resurfaces
When a drone strike killed one of the leaders of al-Qaeda's affiliate in Yemen last year, US intelligence officials thought they also had wiped out the terrorist group's top bomb maker.
Soon it became apparent that Ibrahim Hassan al-Asiri, the brains behind sophisticated bombs that have been used in attempts to attack the US, was still alive. Al-Asiri went underground, knowing the US was after him, particularly after the US killed Anwar al-Awlaki, one of the Yemen group's top leaders. (AP)
