Palestinian labourers from a town in the West Bank have their meal on a construction site near Tel Aviv July 11, 2013. There are two ways for Palestinian workers to cross into Israel every day. Those with work permits can pass through a military checkpoint. Those without have to find a way through the separation barrier, which is made up of mostly fences and some cement walls, snaking its way through the West Bank. Those caught entering illegally risk a fine or imprisonment. Both ways are time consuming but the reward for those who find a job in Israel is four times the amount of pay that they can earn in the West Bank. Picture taken July 11, 2013.
