Under the terms of the deal last October between Iran and the foreign ministers of Germany, the UK and France -- at a time when the US was urging a harder line on Iran -- the Europeans offered to sell nuclear technology to the Iranians if they agreed to stop enriching uranium.
Iran, while asserting its right to enrich uranium, said it would suspend the activity.
A recent report by the agency cast doubt on Iran's claims. It said the Iranian government was continuing to make parts for centrifuges, the machines that enrich, or purify, uranium by spinning it.
The agency's director-general, Mohamed ElBaradei, said it was "premature to make a judgment" about whether Iran's program was military.
