Iran has banned two UN nuclear inspectors from entering the country, according to a state media report.
The report, posted on the website of the state broadcasting company, quotes Ali Akbar Salehi, head of Iran's nuclear department, as saying the Vienna-based International Atomic Energy Agency (IAEA), the UN nuclear watchdog, has been informed of the decision to ban the two inspectors.
The ban is the latest twist in Iran's deepening tussle with the IAEA and the West over its nuclear programme.
The United States says Iran's programme is geared towards making nuclear weapons. Iran denies the charge.
Mr Salehi claimed the two inspectors' latest report on Iran was false and they disclosed its contents before the agency reviewed it.
