But law enforcement sources said that longstanding concerns about al Qaeda in the Arabian Peninsula, an affiliate that has sought to hide bombs in aircraft for a long time, was a factor in the development of the new rule.

A senior law enforcement source also said that intelligence suggests that a Qaeda could be helping ISIS develop smaller explosives.
