ISLAMABAD : Dozens of Afghan refugee families, including women, children and the elderly, gathered in a public park in Islamabad on Saturday after being allegedly evicted from their homes under Pakistan’s crackdown on undocumented migrants. With no aid from authorities or NGOs, they endured police raids, food shortages and the constant fear of deportation to Taliban-ruled Afghanistan. “We have nowhere to go,” said Fahima Khatoon, 45, whose children were born in Pakistan.
