A Tunisian man who was accused last year of plotting to build a U.S.-based terrorism cell has accepted a plea deal.

Ahmed Abassi also was accused of radicalizing a Canadian man charged with conspiring to derail a train that runs between New York City and Montreal.

Abassi pleaded guilty Tuesday to lesser charges of making false statements and possessing an identification document with intent to defraud the United States.

He faces up to six years in prison at sentencing on July 23.
