Pakistan-Afghanistan border crossing overwhelmed as Afghans face expulsion

Thousands of people are flooding Pakistan's northwestern border crossing into Afghanistan after the government's deadline for undocumented foreigners to leave expired. Pakistani authorities have been rounding up undocumented foreigners, primarily Afghans, citing their involvement in militant attacks and crime. Over a million Afghans may have to leave Pakistan or face arrest and forcible expulsion. More than 24,000 Afghans crossed into Afghanistan on Wednesday alone, with thousands more expected to follow.
