UN alarmed by 'violent' Syria demo
One person died during the protest while dozens were wounded.
The UN refugee agency said a "heated demonstration" in Jordan's sprawling Zaatari refugee camp on Saturday turned to "a violent one" after hundreds, possibly thousands of refugees started throwing rocks at a police post.
The agency said that the protest started over a refugee family being held there after police detained them and a driver who tried to smuggle them out of the camp.
The UN said police fired tear gas and there were reports of live ammunition being used.
It said 28 Jordanian policemen were wounded.
Jordan is home to 588,979 registered Syrians refugees, most of them in Zaatari.
