Tens of thousands of Israeli nationalists marched to Jerusalem's Old City Thursday in an annual flag-waving march commemorating Israel's capture of it, as tensions on the Gaza border remained high.Palestinians in annexed east Jerusalem closed their shops and were banned from the Damascus Gate entrance to the Old City, a social hub, to make way for the marchers, some of whom attacked journalists with rocks and bottles, an AFP reporter said.Police said they had made two arrests over the attack, one of an adult and one of a minor.
