When Jalalian was ten years old, she ran away from home because her parents would not allow her to go to school.
Arrest
Jalalian was arrested in July 2007 in the Kurdish city of Kermanshah and transferred to the detention center of the Intelligence Ministry. Her trial before the Court of First Instance took place in December 2008; after conducting a summary trial, the Court found Jalalian guilty and sentenced her to death, on charges of being a member of the Party of Free Life of Kurdistan, a banned Kurdish group: based on her alleged membership of that Kurdistan political party, she was accused of fighting God and given the death penalty. Jalalian has denied the charges. Her death sentence was confirmed by the Iranian Supreme Court in November 2009.
On June 28, 2010, her family stated that in her last phone call, "which was a month ago, Zeynab has mentioned that she is held in Evin Prison”. Since that time, her family or her lawyers had not been able to receive any further information, the authorities responding that her file had been lost. In an interview with the International Campaign for Human Rights in Iran, published on July 1, 2010, Iranian lawyer Khalil Bahramian talks about him being refused to visit Ms Jalalian in prison. In 2010, after being incarcerated into section 209 of the Evin prison for five months, and after a meeting with Tehran Public Prosecutor, Jalalian was transferred back to Kermanshah prison. The Supreme Court of Iran has reduced Jalalian's sentence to life imprisonment. In December 2011, Ms. Jalalian contacted her lawyer to inform him that, according to prison authorities, her sentence had been reduced to life imprisonment. According to the Committee of Human Rights Reporters, Jalalian’s lawyer, Dr. Mohamad Sharif declared in December 2011: “After a long period of follow-up with the Judicial authorities and not being able to receive answers, the Supreme Court overturned the death sentence and changed it to life in prison". In Kermanshah prison, Zeynab Jalalian was verbally informed by judicial authorities that her death sentence had been commuted to imprisonment.
Zeinab Jalalian, along with nine prisoners of ordinary offences, went on hunger strike in protest to being deprived of weekly visits and basic prison facilities in August 4, 2018. The strike ended the day after with no result.
