The UN nuclear watchdog said in a confidential report on Friday that it is increasingly concerned about a uranium enrichment plant at Isfahan that Iran declared last year but has not let inspectors visit. The plant's exact location and whether it holds nuclear material remain unknown to the agency, according to the report seen by Reuters. Iran has not allowed inspectors back to any nuclear facility bombed by Israel and the United States in the 12-day campaign in June last year. Iran International reported the same findings, underscoring the agency's lack of access to Iran's nuclear program.
