The United States says it has yet to confirm reports regarding the leadership succession situation in North Korea.

State Department spokesman Robert Wood told reporters Tuesday that Washington has reviewed speculative reports concerning the succession situation in Pyongyang, but that none of these reports have been confirmed.

On a Reuters report that the North is likely to come back to the six-way nuclear talks now that it has moved to anoint leader Kim Jong-il's third son as his successor, Wood said the U.S. hasn’t seen any sign that Pyongyang is planning to return to the bargaining table.

White House spokesman Robert Gibbs said the National Security Council has yet to finalize a position on the North’s leadership succession issue.
