Palestinians dig through what was once the runway of Gaza's bombed-out airport to collect rubble and gravel needed for construction in the war-ravaged territory, on the outskirts of Rafah, southern Gaza Strip on 21 August 2010. Media reports state that with unemployment extremely high in the Gaza Strip, hundreds of youths work at lifting tarmac near the border area and then fill sacks with the small gravel stones just underneath the black tarmac, which are then sold for building materials. One man said the pay is about 50 Shekels, or about $12, per ton for the gravel. Photo By Abed Rahim Khatib / Flash90
