JERUSALEM -- A former Israeli peace negotiator says thousands of young Jewish and Arab activists from across the Middle East plan to hold an online peace conference this week on Facebook.

Uri Savir says the Yala Young Leaders group will hold its interactive conference on Monday and Tuesday. U.S. Secretary of State Hillary Rodham Clinton, actress Sharon Stone, Barcelona football coach Pep Guardiola, National Basketball Association Commissioner David Stern and others are set to address the virtual gathering.

Savir directs the Peres Center for Peace, a sponsor of the Facebook group. It counts 36,500 members across the region.

Nimrod Ben-Zeev, the site's administrator, says the conference aims to send a message of peace to the region's leaders and create concrete programs, such as online leadership academy.
