The Iranian government says it has the right to decide which international inspectors will be allowed to monitor its nuclear facilities.
A spokesman for Iran's Foreign Ministry said Tehran could reject the inspectors on the basis of their previous activities.
The official, Ramin Mahmanparast, was echoing comments by the nation's nuclear chief Ali Akbar Salehi, who noted Iran had accepted alternate inspectors provided by the International Atomic Energy Agency.
Salehi was quoted as saying that two inspectors rejected by Iran had filed false reports on Iran's nuclear program.
A report released Monday by the IAEA said Iran's objections to certain inspectors are complicating efforts to investigate its nuclear program. The program is at the core of an international dispute over whether the activities have a military component.
