The U.N. atomic watchdog has received new information regarding allegations that Iran may be seeking to develop a nuclear-armed missile, the agency said in a report voicing deepening concern about the issue.
The confidential document signaled the U.N. body’s growing frustration at what it sees as Iran’s lack of cooperation with a long-running investigation into its disputed nuclear program.
It also made clear Iran’s determination to press ahead with sensitive atomic activity despite four rounds of U.N. sanctions since 2006, saying the country had informed the IAEA it would soon start operating a second uranium enrichment plant.
The report looked likely to add to Western suspicions that Iran is secretly bent on building a nuclear weapons capability from its enrichment program, which Tehran denies.
It may also provide the United States and allies with additional arguments for further tightening sanctions on the Islamic Republic, after talks in December and January failed to make any progress toward resolving the dispute.
The IAEA report, obtained by Reuters on Friday, said it remained concerned about possible current activity in Iran to design a nuclear payload.
“Iran is not engaging with the agency in substance on issues concerning the allegation that Iran is developing a nuclear payload for its missile program,” it said.
For several years, the IAEA has been investigating Western intelligence reports indicating Iran has coordinated efforts to process uranium, test explosives at high altitude and revamp a ballistic missile cone in a way suitable for a nuclear warhead.
An official with knowledge of the IAEA’s investigation said the new information, if it turned out to be correct, concerned both Iran’s past and more recent activities.
The report said that based on an analysis of “additional information which has come to its attention since August 2008, including new information recently received, there are further concerns which the agency … needs to clarify with Iran.”
