This makeshift settlement in Pakistan houses Afghan refugees, and lies a short drive from a five star hotel in Islamabad where international VIPs are discussing their future on Monday (February 17). The United States has reached agreement with the Taliban to reduce violence for a week, which could lead to U.S. troops withdrawing from Afghanistan. But the prospect of a peace deal -- perhaps by the end of the month -- is raising questions about the future of one of the biggest refugee populations in recent history, exiled by decades of war. There are about three million refugees in Pakistan, many more in Iran. Many were born abroad, without knowing their homeland.
