6 Million Pushed Back to Afghanistan in Under 3 Years as Aid Runs Dry

Six million. That is the number now attached to Afghanistan's western and southern borders, where buses and trucks have been unloading families from Iran and Pakistan for almost three years without stopping. Since September 2023, roughly six million Afghans have been returned, many forcibly, from those two neighbours in what analysts describe as one of the largest return movements of any nationality in recent decades. ³

Almost half of that total arrived in a single year. In 2025 alone, the pace of returns accelerated so sharply that it now accounts for nearly half of all returns since September 2023, according to the Afghanistan Analysts Network assessment published in June 2026. ³ The concentration in time is what has turned a long-running deportation drive into a shock: border crossings built for a trickle are being asked to process hundreds of thousands in weeks, while villages and cities on the receiving side have no housing, jobs or classrooms ready.

Reporting from the Torkham crossing and from Kabul, the BBC's Lyse Doucet found the human shape of the statistic in children stepping into a country they had never lived in. Many returnees, including children born and raised in exile, were seeing Afghanistan for the first time. ^{2 8} The BBC described the flow as the biggest cross-border movement of people, a measure not of distance travelled but of how many lives were uprooted at once and how completely they must start over. ^{2 8}

The most detailed breakdown available comes from the Afghanistan Analysts Network, which reported on 24 June 2026 that some six million Afghans had been forcibly returned from Iran and Pakistan since September 2023, with almost half of them in 2025. ³ Within that total, 2.26 million people returned from Pakistan, including one million in 2025 alone. ³ Those figures trace a two-front pressure: simultaneous expulsions from the west and the south, landing on the same exhausted reception system.

United Nations figures capture the same surge at lower, shorter-range resolution, which is part of why the overall picture remains contested. UNHCR, cited via TOLOnews on 5 June 2026, reported about 700,000 returns and warned that Afghanistan faces one of the largest population return waves in the world. ⁵ A later UNHCR figure dated 8 August 2026 said more than 600,000 Afghans returned or were forced to return from Pakistan since the beginning of 2026, many via Torkham. ¹⁰ The two counts do not map neatly onto the six-million cumulative total because they cover different periods and corridors, and because no single agency claims to count every crossing.

The daily rhythm helps explain the cumulative weight. Taliban deputy spokesperson Hamdullah Fitrat said in a statement on Monday 15 June 2026 that 472 families totalling 2,523 individuals returned from neighbouring countries in one day, including 375 families or 2,043 individuals through Torkham alone. ⁹ Multiply even a fraction of that daily rate across weeks of coordinated deportation campaigns and the path to millions becomes visible, as does the administrative fiction that each family can be received, registered and resettled in an orderly way.

Iran has been the other engine of return. About 1.5 million Afghans have been driven out by Iran, in a campaign in which some returnees were accused of spying for Israel. ¹¹ That accusation, layered onto economic pressure and longstanding hostility toward undocumented Afghans, has made the western border as fearful a crossing as the eastern one, with families arriving carrying allegations they cannot answer and losses they cannot recover.

What waits on the Afghan side is not a postwar recovery but a second crisis. Returnees face sustained struggles rebuilding lives around shelter, livelihoods and schooling. ³ Those needs arrive amid drought and shrinking foreign assistance, a combination that leaves newly arrived families competing for water, work and aid in communities that already lack them. ³ The UN warning reported in February 2026 was blunt in its direction if not its wording: the return of millions from Pakistan and Iran is pushing Afghanistan to the brink. ⁶

The timing sharpens the strain. The returns are landing five years after the Taliban retook Kabul on 15 August 2021. ⁴ Coverage marking that anniversary in August 2026 framed the period around displacement, deportation and a human rights crisis, not normalisation or absorption capacity. ⁴ Afghanistan in 2026 is ruled by an entrenched authority marking survival after two decades of war, yet it is being asked to reintegrate millions of its own nationals, many of them young, urbanised elsewhere, and unfamiliar with the rules and scarcities that will govern their lives.

The honest problem is that no one can say with precision how many have arrived, who forced whom, or what has been spent to meet the need. The receiving state cannot say how many have arrived and the numbers do not agree, according to Kabul Signal reporting on 7 August 2026 that directly flagged the verification gap. ⁷ There is no exact verified breakdown by country and timing, nor a verified accounting of the share that was forcible compared with voluntary, nor a verified ledger of shelter and aid funding against need. ⁷ In that vacuum, six million functions as the best-supported cumulative estimate rather than a counted population, built from overlapping agency tallies, border reports and analyst synthesis that do not fully reconcile.

That uncertainty does not make the movement smaller. If anything, it explains why the response keeps falling short: planners cannot budget, build or hire against a total that shifts with each source, while families keep arriving whether or not they have been counted. The children at Torkham who had never set foot in Afghanistan are not a statistical artefact. ^{2 8} They are the leading edge of a generation being resettled into drought-hit provinces and crowded cities with schools already full and clinics already rationing care.
