Egyptian authorities have shut down the Cairo office of an Iranian TV network, as the two nations spar over a controversial Iranian film about former Egyptian President Anwar Sadat. A security official says authorities confiscated equipment and shut the office of Al-Alam TV on Monday because it was operating without a license. The official spoke on condition of anonymity because he was not authorized to speak to reporters. However, the head of Al-Alam's Cairo office, Ahmed al-Sayoufi, says the network has been wrongly accused of involvement in the production of the documentary about Sadat. The film, titled "Assassination of a Pharaoh," has caused offense in Egypt, where critics say it portrays Sadat's killer in a positive light.
