Thousands of Jewish nationalists, some of them chanting “Death to Arabs” and other racist slogans, paraded on Thursday through the main Palestinian thoroughfare of Jerusalem’s Old City, in an annual display that caused new friction between Jews and Palestinians in the tense city.

The marchers, who were overwhelmingly male Orthodox teens and young men, were celebrating ‘Jerusalem Day’, which marks Israel’s capture of the Old City 56 years ago. The Palestinians see the event as a provocation. Two years ago, the parade helped fuel an 11-day war between Israel and Hamas militants in the Gaza Strip.
