GENEVA (Reuters) - The U.S. delegation to six-power negotiations with Iran on its nuclear program held bilateral talks with Tehran's delegates on Tuesday in a meeting a senior U.S. official described as "useful."

Undersecretary of State Wendy Sherman, effectively the State Department's third-ranking diplomat, is leading the U.S. delegation. Sherman and other U.S. officials met Iranian Deputy Foreign Minister Abbas Araqchi and other Iranian delegates, a senior State Department official said.
