TORKHAM: Perched on top of lumbering trucks overflowing with all their possessions, Afghan families are streaming back to their home country at unprecedented rates, leaving international organisations scrambling to provide aid as winter approaches. The flow of returnees from Iran and Pakistan this year, estimated by the United Nations to number more than half a million, is straining the capacity of the government and aid agencies, even as violence uproots more Afghans around the country. At Torkham, the busiest border crossing between Afghanistan and Pakistan, nearly 170,000 Afghans have returned this year, according to the UN, many of them citing harassment by Pakistani authorities as relations between the two countries have deteriorated. Islamabad has stepped up pressure to send people back and numbers have risen sharply in recent months as Afghan-Indian relations strengthened and those between India and Pakistan soured. Lines of colourfully decorated trucks pass through the border gate at Torkham, navigating the mountainous passes with returning refugees clinging to piles of household goods, sometimes with a family cow nearly buried in the back. A cluster of white tents only a few hundred meters from the border marks the first facility operated by the UN, the Afghan government, and other aid agencies to provide aid for returnees before they look for a home in a country many have not seen in years. Here, and at other sites nearby, families are offered medical checkups, bundles of basic supplies and food. In September, the UN issued an appeal for millions of dollars of emergency funding to help returning refugees and other internally displaced people in Afghanistan, but so far the fundraising has yet to reach its goal, said Mark Bowden, the UN’s humanitarian coordinator in Afghanistan. “Out of the $150 million that we requested, we’ve only got $48 million so far, and our costs are certainly going to be running quite high over the winter period,” he said. While the winter is usually mild in the area of Nangarhar province where many returning refugees have at least temporarily settled, many others have headed further west to Kabul, where freezing temperatures may take a toll on anyone unable to find accommodation, Bowden said. Escalating friction between Afghanistan and Pakistan flared into brief clashes at the Torkham border crossing in June, the violence symptomatic of a wider decline in relations between both countries that has prompted political and sometimes military confrontations. Both countries accuse each other of harbouring terrorist groups, and Pakistan has been wary of Afghanistan’s deepening ties with notorious Indian intelligence agency Research and Analysis Wing. But Pakistani officials deny there has been systematic harassment of Afghans living in Pakistan and say their country has demonstrated great generosity to the refugee population, despite severe economic problems of its own. While the challenges of helping the returning Afghan refugees requires immediate attention, the international community should work with Afghanistan, Pakistan, and Iran to try to solve the broader problems driving the crisis, said Tadamichi Yamamoto, head of the UN assistance mission in Afghanistan. “This could be a long-term issue, but I think the immediate attention now will define the magnitude of the problem that we have down the road,” he said. “So we need to do it right at the start.” As many as 350,000 Afghan refugees have returned to their war-torn homeland from Pakistan this year, UN data shows, with the torrent of people crossing the border expected to continue. Earlier in October the UN’s refugee agency UNHCR said the number of documented Afghan refugees returning from Pakistan had soared past 200,000. But this week the body’s Office for the Coordination of Humanitarian Affairs (OCHA) in Afghanistan released updated figures that also include the number of undocumented refugees crossing the border. “So far this year, 162,186 undocumented returnees and 207,236 registered returnees (369,422) have returned to Afghanistan from Pakistan,” an OCHA statement said, noting that the majority, some 333,000 people, have returned since July. “If that sounds like a lot, it is,” the statement continued. “Based on current trends, we expect a further 446,000 (both registered and undocumented) Afghans to arrive before year-end.” The influx of refugees threatens to overwhelm Afghanistan, with authorities there already warning of a humanitarian crisis as hundreds of thousands of people flee fighting within the country.
