Palestinian children hold national flags and placards during a protest against the Egyptian decision to close the smuggling tunnels along the Gaza-Egypt border in Rafah, in the southern Gaza Strip, on Sept. 15, 2012. The tunnels trade, which analysts estimate is worth half a billion dollars a year, brings a wide variety of goods, including food, fuel and building materials, into the coastal territory which has been under an Israeli blockade since 2006.
