Israeli police and some 200 Palestinian youths clashed on Tuesday in a part of occupied east Jerusalem where a controversial Israeli archaeological project is underway. Police and border guards fired rubber bullets and tear gas at the demonstrators, some of whom were throwing rocks, witnesses said.Five Palestinians were reportedly injured, and one arrested. A police spokesman said calm was restored after local Palestinian officials called on the demonstrators to disperse, adding that no arrests were made. Palestinians are angered by an Israeli plan to raze 22 Arab homes to make way for an archaeological park, and Palestinian president Mahmud Abbas has urged Washington to block the controversial project.
