more In this Wednesday, April 18, 2012, photo, an Afghan refugee boy, center, sleeps on a bench, while his mother waits her turn to receive free medicine from a clinic, in a slum on the outskirts of Islamabad, Pakistan. Hundreds of thousands of Afghan refugees are in limbo as Pakistan, increasingly frustrated with hosting the world's largest and longest-running refugee population, weighs whether to renew their refugee status by the end of this year.
