Palestinian supporters of Hamas throw stones at Egyptian border police, not seen, during a rally protesting the delay of an international aid convoy from Egypt, in Rafah southern Gaza Strip, Wednesday, Jan. 6, 2010. Egyptian security forces and Palestinians clashed at the Gaza border over the delay of the convoy, killing one Egyptian border guard and wounding 11 Palestinians. The incident further raises the tension between Egypt and the Hamas rulers of the Gaza Strip who see Cairo's attempts to seal the border as a direct threat to their survival, particularly a new effort to build a steel wall blocking cross-border tunnels.
