Iran has given the International Atomic Energy Agency more access to its nuclear sites. A new report on Iran by the IAEA finds evidence of slowed uranium enrichment and of increased cooperation on the monitoring of known nuclear installations. On the other hand, a confidential IAEA report said, Iran also raised the number of installed, though not all enriching, centrifuge machines by some 1,000 to 8,308. The UN said that it was fully aware of the report. The IAEA report will form the basis for six-power talks on September 2 to look into stricter UN sanctions on Iran over its nuclear activity.
