Jordanian security forces fired tear gas and used armoured vehicles to drive back thousands of anti-Israeli protesters along the border area overlooking the occupied West Bank.
More than 20,000 protesters had driven to the border town of South Shouneh, 7 km from the Allenby Bridge, in a symbolic march to denounce Israel and rally for the right of return of Palestinian refugees.
Witnesses said the clashes began when dozens of anti-riot police prevented the marchers from proceeding to the town centre, first using water cannon and then tear gas.
Some protesters hurled stones as hundreds of anti-riot police fired more tear gas in a stampede which left dozens injured.
The demonstrators urged Jordan's King Abdullah to open the border post along the Jordan River which overlooks Jerusalem to allow volunteers to wage attacks against Israel.
