WASHINGTON (Reuters) - The United States on Thursday black-listed a number of additional companies and people under sanctions aimed at Iran's nuclear program, U.S. officials said in a statement.

Treasury and State Department officials said the move shows the recent agreement reached in Geneva over Iran "does not, and will not, interfere with our continued efforts to expose and disrupt those supporting Iran's nuclear program or seeking to evade our sanctions."
