The setting of a timetable follows Iran's promise late last year to resolve all issues concerning its nuclear program.
Iran is already under UN Security Council sanctions over its controversial nuclear program, which Western nations suspect is being used as a cover for weapons development. Now, the US is advocating additional penalties, despite a recent US intelligence report that said Iran had stopped its weapons program as of 2003, reports the Associated Press.
ElBaradei also was given new information on Iran's "new generation of centrifuges" during weekend talks with Iranian leaders, said his spokeswoman, Melissa Fleming. That issue is a priority for the agency as it tries to establish how far advanced Iran is in developing the technology.
Announcing the deadline, Fleming spoke only in general terms, without mentioning what was being now probed by agency experts under a plan agreed to last summer. But diplomats said that investigation was now in its final stage, focusing on programs with possible weapons applications.
... Separately, however, a senior diplomat expressed doubt ElBaradei was able to persuade the Iranians to freeze enrichment and noted Western efforts for additional U.N. sanctions against the Islamic republic would continue unless that condition was met. Both spoke on condition of anonymity because they were not authorized to comment publicly on the issue.
