Updated 6:30 pm: Israeli occupation forces shot and wounded 10 Palestinians near the West Bank town of Ramallah Friday during a protest over the killing of a teenager, Palestinian medics and security sources said.
In Gaza, meanwhile, medics said five more Palestinians were wounded by Israeli gunfire near the border in two separate incidents.
Security sources said the Palestinians were hit by live rounds on the outskirts of Jalazun refugee camp and hospitalized in Ramallah, including one with serious injuries.
Hundreds of Palestinians took part in the protest, many of them hurling rocks at the soldiers.
The demonstration was called to protest at the Israeli army's killing on Wednesday of Mohammed Mubarak, a 19-year-old from Jalazun working on a project funded by USAID and son of the camp's locally elected leader.
The army said he was shot dead near a Jewish settlement outside Ramallah after having opened fire at them, but witnesses insisted he was unarmed.
Palestinian housing and public works minister Maher Ghneim condemned what he branded the "cold-blooded killing" of a laborer who was working on a project run by the ministry in coordination with USAID.
Ghneim said the youth had been "carrying a sign to direct the traffic" when he was shot.
Separately in Gaza, medics said a 27-year-old farmer is in "moderate condition" after being shot in the foot by occupation forces in the town of Beit Lahiya, Ma'an news agency reported.
Later, occupation forces shot four other Palestinians east of Jabaliya, Ma'an said.
"Two riots erupted near the security fence in northern Gaza. In one riot, 50 Palestinians crowded in a prohibited area and hurled rocks at IDF soldiers at the scene," Ma'an cited an occupation authority as saying.
Friday's shootings comes after early morning Israeli air strikes left seven people injured in the besieged strip.
Israeli soldiers shot dead a young Palestinian protester on the Gaza border last week.
A total of 27 Palestinians were killed by the occupation army in the West Bank and nine in Gaza in 2013, three times more than the previous year, figures from Israeli rights watchdog B'Tselem showed.
