Tunisian man is held in terror plot

NEW YORK — A Tunisian man accused of radicalizing a Canadian resident charged in a plot to derail a train has been charged with trying to stay in the United States illegally to build a terrorism cell for international acts such as poisoning a water system with bacteria, authorities said Thursday.

Law enforcement authorities had watched Ahmed Abassi since he arrived in the United States from Canada in mid-March and arrested him on April 22 at John F. Kennedy International Airport, authorities said. Abassi met regularly with an undercover FBI agent and met with another Tunisian citizen who later was arrested in Canada in the plot to derail the train, they said.
