A girl attends a Kalasha language class at the Kalasha Dur school and community centre in Brun village, located in Bumboret Kalash valley October 13, 2011. Nestled among the valleys of Pakistan's mountainous northwest, the Kalash are a tiny religious community that claim descent from Alexander the Great's army, and say they are under increasing pressure to convert to Islam. The Kalash, who number about 3,500 in Pakistan's population of 180 million, are spread over three valleys along the border with Afghanistan and are known for their distinctive dress, vibrant religious festivals, and polytheism.
