Palestinians hold a flag and throw a stone during clashes with Israeli troops at Qalandiya checkpoint

Palestinians hold a flag and throw a stone in front of a mural depicting the late Palestinian leader Yasser Arafat on the controversial Israeli barrier, during clashes with Israeli troops at Qalandiya checkpoint, near the West bank city of Ramallah September 23, 2011. Israeli security forces were on high alert after Friday prayers at a major Muslim mosque in Jerusalem and surrounding Palestinian districts given a deepening diplomatic deadlock over the Palestinians’ application for U.N. membership.
