Jose Padilla, a U.S. citizen held without charges for more than three years on suspicion of plotting a "dirty bomb" attack in this country, has been indicted on three counts alleging he conspired to "murder, maim and kidnap" people overseas.
The indictment naming Padilla and four others was unsealed Tuesday after being returned last week by a federal grand jury in Miami. While the charges allege Padilla was part of a U.S.-based terrorism conspiracy, they do not include the government's earlier allegations that he planned to carry out attacks in America.
