Thousands of Afghan families, fearing an uncertain future, have begun pouring into Afghanistan amid a fresh push from Pakistan against what officials describe a “crackdown" on undocumented aliens.Islamabad had set the July 10 deadline for what the authorities call “undocumented” Afghans to leave the country.The move comes amid a broader push by authorities around the world who have been pushing Afghans who fled their country to return home.In Pakistan alone, more than 2.5 million Afghans have been deported since October 2023, the year when Islamabad announced the deportation policy.“An average 400 to 600 families are crossing the Torkham border daily,” said Islam Badshah, a volunteer from the Jamrud region in Pakistan’s Khyber tribal district, who provides free food, medicines and other basic items to the departing families.Torkham is the main crossing point between Afghanistan and Pakistan.Badshah, who collects donations from locals to continue his welfare work, says a majority of the families hold UN-issued registration cards, but Pakistani authorities say only Afghans with valid-stay visas such as student, business, or visits in their passports will be allowed to stay.Afghans Being Sent HomeZia Rahman was among the hundreds of families who have arrived at the Hamza Baba Transit Center for Afghan refugees near the border on July 13.With his family awaiting clearance from the authorities to cross the border, Rahman told RFE/RL that he and his elder brothers were born in Pakistan and are being forced to a country they don't know.“Neither my children, nor those of my brothers ever visited Afghanistan,” he said. “We are heading to an uncertain future --- how to get jobs and if our children will be able to attend schools?”the 36-year-old said.
