In this Sunday, Sept. 2, 2012, photo, Pakistani Christians sit on a rooftop of a home performing their daily prayer, in a Christian neighborhood in Islamabad, Pakistan. The plight of Pakistan's Christian minority has received renewed focus in recent weeks because of the arrest of a young, mentally challenged girl accused of insulting Islam. Christians are believed to make up two to three percent of Pakistan's population of 190 million people, and many face daily discrimination and hold low-level jobs, such as street sweeping. They often live in slums and celebrate their religion in humble, makeshift churches. (AP Photo/Nathalie Bardou)
