Special report: Iran Nuclear Crisis 

    TEHRAN, Aug. 6 (Xinhua) -- A delegation from the International Atomic Energy Agency (IAEA) arrived in Iran on Monday to work on the regulations under which inspections of Iran's nuclear sites will be carried out, the official IRNA news agency reported.

    "A technical delegation from the IAEA arrived in Tehran on Monday and will meet Iranian Atomic Energy Organization officials this afternoon," an unidentified official was quoted as saying.

    During their four-day visit, the IAEA experts are supposed to discuss drawing up an action plan for inspections of the Natanz uranium enrichment facility within the framework of the nuclear Non-Proliferation Treaty, the official said.

    Officials from Iran and the UN nuclear watchdog have negotiated in Tehran and Vienna to make a plan to solve the remaining problems over Iran's nuclear issue.

    On March 24, the UN Security Council unanimously adopted a new resolution, the second punitive one, with tougher sanctions to pressure Iran to suspend its uranium enrichment activities.

    However, an IAEA report in May said that Iran continued to resist the UN Security Council ban on enrichment and was expanding its activities instead.
