Religious intolerance and violence against minorities may be on the rise in Pakistan, but authorities in the deeply conservative northwest Khyber Pakhtunkhwa province are hoping for a tourism boost -- thanks to the area's rich Buddhist heritage. KP is increasingly being viewed as the heartland of militants who have killed thousands in recent years and it is also home to some of the most important sites of Mahayana Buddhism. Last year a group of around 20 Buddhist monks from South Korea made the journey to the monastery of Takht-i-Bahi, close to the tribal areas that are a haven for militants.
