evidence: VIENNA (AP) — The U.N. atomic watchdog said Thursday it believes that Iran has further increased its stockpile of highly enriched uranium and criticized Tehran for continuing to bar the agency’s officials from accessing or monitoring Iranian nuclear sites. In its quarterly report, the International Atomic Energy Agency said that according to its assessment, as of Oct. 22, Iran has an estimated 62.3 kilograms (137.3 pounds) of uranium enriched to up to 60% fissile purity. That amounts to an increase of 6.7 kilograms since the IAEA’s last report in September. [...] The IAEA report, which was seen by The Associated Press, also estimated that as of Oct. 22, Iran’s stockpile of all enriched uranium was at 3673.7 kilograms — a decrease of 267.2 kilograms since the last quarterly report in September.
