Afghanistan urged Iran on Thursday to stop deporting its citizens during the winter months, saying doing so could cause a humanitarian disaster. Iran has said it plans to deport all of the nearly 1.5 million illegal Afghan migrants it says are living in the country. It says many of the migrants are there for economic reasons. Iran is also trying to persuade the some 910,000 registered refugees from Afghanistan to return home. Many of the migrants have no homes in Afghanistan and could be forced to live outside on their return.
