TEHRAN (AFP) - US-Iranian reporter Roxana Saberi, who has been handed an eight-year jail sentence on charges of espionage, has been on hunger strike for the past five days, her father told AFP on Saturday. She has started (a hunger strike) and today is the fifth day, Reza Saberi said. Her lawyer lodged an appeal over the sentence today, he added. Saberi, 31, was convicted by an Iranian revolutionary court in a closed-door trial last week of spying for the United States, which along with Israel is Tehrans main foe. Saberi has been held since late January, when she was initially reported to have been arrested for buying alcohol, an illegal act in the Islamic republic. US-born Saberi, who is also of Japanese descent, has reported for US National Public Radio, the BBC and Fox News, and has lived in Iran for the past six years.
