In this Monday, January 19, 2015 photo, a Pakistani refugee schoolgirl attends class at Gulan camp, some 20 kilometers (12 miles) from the border in the restive Khost province, Afghanistan. For decades Afghans have fled into Pakistan to escape war and upheaval, but in recent months the tide has reversed, with some 60,000 Pakistanis - more than half of them children – taking refuge in the Gulan camp.
