The head of the UN's International Atomic Energy Agency (IAEA) said he saw "no radical change" in Iran's nuclear program since Hassan Rohani became president in August.
Yukiya Amano, who returned from a trip to Iran on November 12, told Reuters in an interview that Iran is still enriching uranium up to 20 percent concentration. Amano added that Iran still has "quite a lot to do" to complete construction of the Arak research reactor, which will produce plutonium, another potential fuel for atomic weapons.
The IAEA is expected to issue its next quarterly report on Iran's nuclear activities by the end of the week.
Iran rejects accusations that it seeks to build nuclear weapons, saying that its nuclear program is entirely for peaceful purposes.
