Vienna, April 6 (NNN) : International Atomic Energy Agency (IAEA) chief Mohammad ElBaradei has accused Iran of not co-operating as openly and quickly as it should to dispel claims that it wants to build nuclear weapons.
He said he hoped to make it clear during his visit to Tehran beginning Tuesday that restoring and accelerating the pace of co-operation was in everyone's interests.
ElBaradei added that he hoped to cover two key issues during his talks: the origins of the highly-enriched uranium found in the country; and details about advanced nuclear centrifuges that can be used to produce weapons-grade material.
"We need to satisfy ourselves that there are no undeclared activities that have taken place in Iran," ElBaradei said. "I and the international community would like to bring the issue to a conclusion. It obviously cannot go on forever."
His remarks came after Britain, France and Germany expressed concern last week over Iran's announcement that it was resuming uranium conversion - a crucial stage in the production of both nuclear weapons and nuclear fuel.
Reacting to the criticism, Iranís UN ambassador Pirooz Hosseini told a news agency that the plant near Isfahan was not in breach of Iran's commitment to suspend uranium enrichment.
Iran insists that its nuclear programme is peaceful and only aimed at producing electricity.
But analysts in the US and elsewhere have expressed concern that Iran is not revealing all of its activities.
