Photographs of killed students of Syed Al-Shahada School are displayed on the gate of a mosque in Dasht-e-Barchi neighborhood of Kabul, Afghanistan, Tuesday, June 1, 2021. After the collapse of the Taliban 20 years ago, Afghanistan's ethnic Hazaras began to flourish and soon advanced in various fields, including education and sports, and moved up the ladder of success. They now fear those gains will be lost to chaos and war after the final withdrawal of American and NATO troops from Afghanistan this summer. (AP Photo/Rahmat Gul)
