A senior Iranian nuclear negotiator says his country is taking a "new approach" with the U.N.'s nuclear agency, which is concerned about allegations that Tehran secretly worked on atomic arms.

Deputy Foreign Minister Abbas Araghchi offered no details ahead of a meeting Monday with Yukiya Amano, the head of the International Atomic Energy Agency. But his remarks suggested that Iran was coming to deadlocked talks between the agency and Iranian diplomats with fresh proposals.

Those talks resume later Monday. IAEA attempts to probe the allegations of covert Iranian nuclear arms development have been stalled for about two years.

Iran says it does not want — and never worked on — such weapons.

Amano described his meeting as important in addressing "the outstanding issues regarding Iran's nuclear program."
