The United States reiterated on Tuesday that Iran must abide by international agreements and "come clean" with the International Atomic Energy Agency (IAEA).

"They (Iran's government) made some agreements, they need to abide by those agreements and act in a good-faith way in the negotiations," White House spokesman Scott McClellan told reporters.

"They need to come clean and cooperate fully with the International Atomic Energy Agency.

"We continue to support the European Three's efforts to resolve this in a peaceful and diplomatic way," McClellan said, referring to diplomatic efforts by Britain, France and Germany to persuade Iran to give up its nuclear program.

The White House spokesman made the remarks after the IAEA said earlier Tuesday it had received a letter from Tehran saying it would resume nuclear fuel research next week.

The UN atomic energy agency on Tuesday urged Iran to "maintain its suspension of all enrichment-related activity" after receiving a letter from Tehran announcing the resumption of nuclear fuel research.
