In this photo taken on Friday, June 27, 2014, Pakistani displaced tribal children suffering from dehydration and gastroenteritis lie on beds at a local hospital in Bannu, Pakistan. The rugged Pakistani region of North Waziristan emerged as a hotbed of polio infections after Taliban militants in the isolated area banned immunizations. Now the Pakistani government's offensive against the militants has sent a half-million refugees fleeing the territory, creating both perfect conditions for the disease to spread and a golden opportunity to immunize many thousands of people.
