The trio who were picked up in the Afghan capital of Kabul were detained for six hours. They underwent fingerprinting and some of their equipment was confiscated, according to the report.
The report said that the three were in Kabul to film scenes of the election process.
IRIB reporters have in the past been arrested in Irans western neighbour Iraq on charges of being Tehrans spies while working under the pretext of news production. Mostafa Darban, then the bureau chief of Iran’s official news agency, was held for more than two weeks by Baghdad police in August 2004.
