BALTIMORE, Maryland (AFP) — Two Roman Catholic nuns whose non-violent action against nuclear weapons landed them with prison sentences returned home to Baltimore to learn they had been listed as terrorists, they said Friday.

Sister Ardeth Platte, 72, and Sister Carol Gilbert, 60, came back from two weeks out of town to find letters from the Maryland State Police saying they had been wrongfully listed as suspected terrorists in a federal database in 2005-2006.
