WASHINGTON/NEW YORK (Reuters) - The United States said on Saturday it will send its No. 2 diplomat to Geneva to meet senior Iranian officials on Monday and Tuesday in what appeared an effort to break a logjam in wider negotiations over Tehran's nuclear program.

    Deputy Secretary of State Bill Burns, who led secret U.S.-Iranian negotiations that helped bring about a Nov. 24 interim nuclear agreement between Iran and the major powers, will head a U.S. delegation. Under Secretary of State Wendy Sherman, the primary U.S. negotiator with Iran, will accompany him on a team that will include senior White House national security staff.
