VIENNA — A senior UN official announced progress Friday in stalled efforts to resume an inquiry on suspicions that Iran may have worked to develop nuclear arms, saying the investigation could be restarted by early next year.
Herman Nackaerts of the International Atomic Energy Agency spoke of progress after returning from talks in Tehran, saying his team was ‘‘able to make progress’’ and the IAEA expects to ‘‘start implementing’’ an agreement on the investigation shortly after new talks in Tehran on Jan. 16
He acknowledged that a key IAEA request — a visit to a site linked to suspected nuclear weapons research — was again denied. But he said he expected IAEA inspectors to be allowed to go to Parchin, a military base southeast of Tehran, and follow up on suspicions it might have been used in arms-related experiments.
Iran’s Ali Asghar Soltanieh spoke of “constructive talks. ’’
