Afghanistan will take back all its citizens being deported from Germany as the European country struggles to accommodate hundreds of thousands of refugees and other migrants who have arrived there this year, a Kabul official said. Afghans currently make up the second largest nationality, after Syrians, arriving in Europe. So far this year, an estimated 120,000 Afghans have left the country, legally and illegally, according to authorities. The International Organization of Migration says more than 76,000 Afghans have migrated to Europe so far in 2015. Germany, a longtime contributor to international forces in Afghanistan and with currently 944 soldiers in NATO's support and training mission there, has increasingly been feeling the pressure of the rising numbers of people coming in. Last week, Germany's interior minister complained of an "unacceptable" influx of Afghans from relatively safe areas of their country, and warned that many of them would have to return home. The minister, Thomas de Maiziere, said Afghans arriving in Germany included "increasing numbers of members of the middle class — including many from Kabul." It isn't clear how many Afghans Germany might try to send back. However, German officials have been keen to stress that only people genuinely fleeing war and persecution are entitled to asylum, and that economic migrants must leave the country. Fewer than half of the Afghans who apply for asylum in Germany are granted it. As a signatory to the Geneva Convention, Afghanistan is obliged to accept its citizens whose asylum applications have been rejected, deputy presidential spokesman Zafar Hashemi said, adding that President Ashraf Ghani and German Chancellor Angela Merkel discussed the issue recently. Afghan Minister for Refugees and Repatriation Hossain Alemi Balkhi has disapproved of Germany's decision to return the Afghans, saying in a recent interview with The Associated Press that Kabul is "against the forced exile of any people from any country back to where they came from." "The problem that caused them to leave Afghanistan in the first place has not been solved — there is still war, conflict, insecurity," he said. However, the minister's international adviser, Rohullah Hashimi, said on Monday that Ghani's decision will be implemented and that a reintegration plan for voluntary refugees would be extended to deportees.
