From the Guardian:
The charges against Nazar Ahari are among the most serious that can be levelled in Iran: muharebeh (enmity against God), a crime, in theory punishable by death, originally intended to be used against armed gangs and pirates, not dissidents.
Nazar Ahari is also charged with assembly and collusion aiming to commit a crime, propagating against the regime and disrupting public order. But perhaps most dangerous among the allegations – strongly denied both by her family and her organisation, the Committee for Human Rights Reporters – is of "relations" with the banned Mojahedin e-Khalq group, which is accused by the Iranian regime of terrorist activities. Her family says that she deplores the organisation.
Arrested twice since the disputed Iranian elections in June 2009 and held in the notorious Evin prison, in north-west Tehran, Nazar Ahari has been kept largely incommunicado since December, when she was arrested with several other women activists on her way to the funeral of Grand Ayatollah Hossein Ali Montazeri in the city of Qom. Also detained was Mahboubeh Abbasgholizadeh, another prominent women's rights activist and film-maker, who has since left Iran and was sentenced in absentia to two-and-a-half-years in jail and 30 lashes for her part in a 2007 protest.
