The report also said Iran handed over documents that contained detailed instructions on how to enrich uranium that could be used to make nuclear bombs.
The report did offer words of praise for Iran's increased cooperation with IAEA experts.
But IAEA chief Muhammad el-Baradei said in the report that "Iran's full transparency is indispensable and overdue."
In Paris, French Foreign Ministry spokesman Jean-Baptiste Mattei criticized Iran's decision to start processing a new batch of uranium. Mattei said the decision is a step in the wrong direction.
Iran confirmed today that it started converting uranium ore.
