The youngest person in the country to be arrested on terrorism charges appears likely to be deported to his native Pakistan after pleading guilty in federal court on Friday, his lawyer said.

Mohammed Khalid, 18, pleaded guilty to conspiring to provide material support to terrorists in charges related to the “Jihad Jane” case, which rose to national prominence when Colleen R. LaRose, who lived in Southeastern Pennsylvania, was arrested on charges that she planned violent jihad attacks through Internet forums where she called herself Jihad Jane. Khalid was arrested when he was 17.
