About 100 Palestinians gathered along the fence separating Israel from the northern Gaza Strip Friday evening, entering a zone that is off-limits to all except the Israeli military.

IDF forces fired tear gas to disperse the crowd, Israel Radio reported. One Palestinian was wounded by Israeli fire, though it remained unclear Friday night whether he was injured by the gas or by another form of ammunition.

The incident comes amid a series of violent riots by Palestinians that have been put down by Israeli security forces.

On Thursday, some 2,000 people marched in Hebron, carrying photos of prisoners and waving Palestinian flags, and another 1,000 protested in the northern city of Nablus.

Palestinian Authority security forces were unable to prevent the marchers from drawing close to the Jewish enclave in Hebron and dozens of demonstrators began throwing rocks at an IDF post in the area.

Israeli security forces used tear gas, stun grenades, and other riot control methods in an effort to push the rioters back.

On Wednesday, riots broke out on the Temple Mount compound, as Palestinians protested a visit to the holy site by Jewish pilgrims and tourists.

Dozens of Palestinian protesters and an Israeli policeman were wounded during clashes, the second such incident this week.

Police arrested six Palestinians overnight in connection with the riots.

Police said they responded with stun grenades after Palestinians threw “stones and firecrackers” when the walled compound’s gates were opened. A small number of Jewish visitors had toured the site before the violence began.
