GENEVA (AP) — The U.N. refugee agency says the return of millions of Afghans from neighboring Pakistan and Iran is pushing Afghanistan to the brink. UNHCR describes it as an unprecedented scale of returns. A total of 5.4 million people have returned to Afghanistan since October 2023, mostly from neighboring Pakistan and Iran. UNHCR’s Afghanistan representative Arafat Jamal gave the figure on Friday, speaking to a U.N. briefing in Geneva via video link from Kabul. He says last year alone, 2.9 million people returned to Afghanistan and notes it was the largest number of returns to any country the UNHCR has witnessed. Pakistan and Iran launched crackdowns in 2023 to expel migrants without documents.
