The Human Rights Activists-Iran website was brought to my attention by an Iranian activist I met at the HR in Iran Forum I attended.  It has occasional updates available in English.  Just a quick browse gives an idea of the issues and the ongoing abuses by the Iranian government.

Another site that puts out weekly human rights bulletins on the ongoing human rights situation in Iran is Human Rights & Democracy International, Pedia.  It also hosts a compelling and disturbing photo gallery.
