Clashes along the Israel-Gaza border on Friday between Palestinian demonstrators and Israeli soldiers injured four Palestinians, the Israeli army said.
Health Ministry spokesman Ashraf al-Qedra said 13 protesters were wounded by live ammunition and tear gas canisters fired by the soldiers. None of the injuries are life-threatening, he said.
The Palestinian news agency Maan reported nine were wounded, one seriously.
The IDF said the soldiers fired on the protesters after they tried to sabotage the border fence.
Dozens of Palestinians were holding the their weekly demonstration near the coastal enclave's north-east border with Israel when the violence erupted.
On Thursday, a 26-year-old Palestinian man was killed and two others were injured near the border. Security officials in Gaza said the three were local workers out collecting gravel when they were shot by Israeli soldiers.
The Israeli army said the Palestinians were trying to sabotage the fence.
Israel established several years ago a 300-meter no-go zone within the borders of the Gaza Strip, and Israeli soldiers immediately open fire on any Palestinian that encroaches upon the area.
