They said such a step is vital to hold perpetrators of past and ongoing abuses accountable.
In an open letter, 107 Afghan civil society groups and international rights organisations said Afghans have faced widespread abuses under Taliban rule over the past four years. They cited extrajudicial killings, torture, enforced disappearances, systemic discrimination against women and girls, bans on their education and work, exclusion from public life, and persecution of minorities including Hazaras, Shias, Sikhs and Hindus. The groups also noted pressure on activists, journalists, artists, lawyers and judges.
Amnesty International, Human Rights Watch, the International Federation for Human Rights and the International Bar Association were among the signatories.
The groups said decades of impunity had fuelled repeated atrocities in Afghanistan. They argued that only an independent body tasked with collecting evidence, investigating abuses and pursuing accountability could end what they described as a cycle of violence.
