There is a mounting humanitarian emergency on the border between Afghanistan and Pakistan. Since October, hundreds of thousands of Afghans living in Pakistan have fled back to Afghanistan. They are being forcibly repatriated by the Pakistani government which began a crackdown on so-called illegal immigrants, compelling the expulsion of over three hundred thousand Afghans in just the last few weeks.  On the line to explain the unfolding humanitarian crisis is Samira Sayed-Rahman, director of policy advocacy and communications for The International Rescue Committee in Afghanistan. We kick off discussing the reasons for Pakistan's sudden crackdown and then discuss the crisis this is generating inside Afghanistan. We also discuss the complications of international humanitarian relief work in Afghanistan under Taliban rule.
