UN agencies have reported a sharp increase in Afghans returning home since Pakistan launched a crackdown on people living in the country illegally. They urged Pakistan to suspend the policy before it was too late to avoid a “human rights catastrophe.” Pakistan earlier this month said it will arrest and deport undocumented or unregistered foreigners after October 31. Two provinces bordering Afghanistan have set up deportation centers. The government says the campaign is not aimed at a particular nationality, but it mostly affects Afghans who make up the bulk of foreigners living in the country.
