Slain hostage's mother wants kidnappers held accountable

The mother of slain hostage James Foley says she wants two British men who were part of the Islamic State cell that killed her son to be tried and imprisoned for the rest of their lives.

Diane Foley welcomed the capture of the men who were part of a group known as "The Beatles" because of their British accents.

Foley told the BBC on Friday that the arrests announced Thursday won't bring her son back, but "hopefully it protects others from this kind of crime."

She says "their crimes are beyond imagination. They really have not done anything good in the world, so I think they need to spend the rest of their life being held."

James Foley was killed on Aug. 19, 2014, after being held hostage for several months.
