 Turkish authorities have captured 133 illegal migrants near the country's eastern border with Iran over the past two days. Concerns over a potential new influx of migrants into Turkey from Afghanistan have been mounting in recent weeks. It comes as violence between the Afghan government and the Taliban has searched since a withdrawal of U.S. and NATO forces. The U.N. refugee agency estimates 270,000 Afghans have been displaced inside the country since January. This brings the number of people forced from their homes to more than 3.5 million.
