Obama poised to unveil counterterrorism reforms

US President Barack Obama on Tuesday plans to unveil reforms aimed at thwarting future attacks like the attempted Christmas Day airliner bombing, as he seeks to limit political fallout from the incident.

Obama will outline an initial series of changes, including enhancements in much-criticized "watch-lists" of terrorism suspects, after he meets with intelligence chiefs and other top security advisers, an administration official said. (Reuters)
