On the occasion of 29 November, International Day of Women Human Rights Defenders, the Women Human Rights Defenders International Coalition calls on the Iranian authorities to release Nasrin Sotoudeh, a lawyer and defender of women’s human rights, detained since 4 September 2010 in Evin Prison, Tehran. Sotoudeh has been held in solitary confinement where she is at risk of torture or other ill treatment, since her arrest. In protest at her detention and treatment, Sotoudeh went on hunger strike between 31 October and 15 November 2010.
