A top homeland security official says authorities are confident a terrorist plot in central Ohio has been foiled. An indictment accuses Somali native Nuradin Abdi of conspiring with an admitted al-Qaida member and others to bomb a shopping mall in the Columbus, Ohio, area. Abdi is in a federal lockup in Columbus.

Homeland Security Department Undersecretary Asa Hutchinson wouldn't give details on how far the plot may have progressed. But he tells NBC's "Today" show it's clear "overt steps" were taken to support terrorist activities. Hutchinson says federal officials believe the plot has been "completely thwarted" -- and that there's no longer a threat to shopping malls in Ohio. Abdi's family says he's innocent.
