The agency also confirmed today that Iran has started preparations for enriching uranium.
The details come in a new report to the IAEA's Board of Governors. The report is to be discussed at an emergency meeting of the board on 2 February, which is expected to refer Iran to the UN Security Council.
Uranium enrichment is a process that produces fuel for use in nuclear reactors. It can also produce material for atomic weapons.
