TEHRAN, Iran -- Iran's state TV says authorities have detained an Asian reporter for asking suspicious questions about the country's disputed nuclear program.

The report did not identify the reporter by name or nationality. His two Iranian assistants were also detained.

The report says the journalist asked people in Tehran for their views on whether Iran's nuclear program had a military dimension and on Iran's relations with Russia.

Monday's report said their case was sent to the judiciary.

The U.N. Security Council, including Russia and China, imposed a fourth set of sanctions on Iran in June after it refused to halt key aspects of its nuclear program.

The West fears the program is aimed at weapons production, a charge Iran denies.
