The stabbing, the latest in a month-long spate of attacks, occurred on the sidelines of clashes between Israeli troops and Palestinian stone-throwers after Friday prayers in the West Bank city of Hebron.
The incident heightened concerns among journalists about their safety.
The Foreign Press Association for Israel and the Palestinian territories said it “marks a worrying development” that demands all media operate with greater caution.
In Nablus, another West Bank city, Palestinians firebombed a site revered by some Jews as the tomb of the biblical figure Joseph, an attack condemned as “irresponsible” by Palestinian president Mahmoud Abbas.
In the past month, eight Israelis were killed in Palestinian attacks, most of them stabbings. During the same period, 34 Palestinians were killed by Israeli fire — 15 labelled by Israel as attackers, and the others in clashes between stone-throwers and Israeli troops.
