Palestinian men who were prevented from reaching the Al-Aqsa Mosque pray during Friday prayers outside Jerusalem's Old City, Friday, March 19, 2010. Palestinians in east Jerusalem and the West Bank lobbed rocks at Israeli security forces, set garbage bins and tires ablaze and torched an Israeli flag in a new outbreak of violence over contested Jerusalem building plans and unsubstantiated rumors about threats to the city's holiest shrine.
