The first day of April is traditionally a day of fun and laughter in Britain. For most Iranians it is Sizdah-Bidar – a time of family, picnics, and outdoor celebration. But for Iran's seven Baha'i leaders, it has another meaning: 10,000 cumulative days of unjustified imprisonment, with no prospect of release until 2028. Shut away from the world, their "family" is now the hundreds of other prisoners of conscience that languish in Iran's prisons. The seven are distinguished for their services to society, not criminality, yet they now survive in cramped, pestilential conditions, lacking essential medical care. Their suffering is emblematic of the human rights crisis in Iran. An international campaign is being launched to raise awareness of their plight.
