Protesters hold placards and gather to demand justice for an 18-year-old woman who was killed after she was set on fire for refusing to drop sexual harassment charges against her Islamic school's principal, in Dhaka, Bangladesh, Friday, April 19, 2019. Nusrat Jahan Rafi told her family she was lured to the roof of her rural school in the town of Feni on April 6 and asked to withdraw the charges by five people clad in burqas. When she refused, she said her hands were tied and she was doused in kerosene and set alight. Rafi told the story to her brother in an ambulance on the way to the hospital and he recorded her testimony on his mobile phone. She died four days later in a Dhaka hospital with burns covering 80% of her body. (AP Photo/Mahmud Hossain Opu)
