This report analyzes the severe decline of freedom of religion or belief since the Taliban’s takeover in August 2021 and their de facto rule over Afghanistan. The Taliban’s imposition of their narrow interpretation of Sunni Islam poses a grave threat to the religious freedom and all Afghans who do not subscribe to that interpretation. The Taliban’s harsh enforcement of its religious interpretation violates the religious freedom of minorities, women, members of the lesbian, gay, bisexual, transgender, queer, and intersex (LGBTQI+) community, Afghans with differing interpretations of Islam, and Afghans who follow no religion. Despite continued promises to protect all ethnic and religious communities residing in Afghanistan, the Taliban de facto government has been unable to provide safety and security to religious minorities against attacks from Islamic State-Khorasan (ISIS-K). While some religious minority communities face the threat of extinction, others struggle to practice their faith in hiding due to fear of reprisal.
