In this Monday, Sept. 30, 2013 photo, a Palestinian worker rests inside a smuggling tunnel in Rafah, on the border between Egypt and the southern Gaza Strip. Since the summer, Egypt's military has tried to destroy or seal off most of the smuggling tunnels under the Gaza-Egypt border, a consequence of the heightened tensions between Cairo and the Hamas government in Gaza. The tunnels once employed thousands of young men in Gaza. By early September, with most tunnels closed, only few tunnel workers reported to their jobs for maintenance work. Some mask their faces with shirts to avoid identification while working, for fear of repercussions in case they were to travel to Egypt in the future.
