In Gaza, meanwhile, medics said five more Palestinians were wounded by Israeli army gunfire near the border fence with Israel.
The sources said the Palestinians in the West Bank were hit by live rounds on the outskirts of Jalazun refugee camp and hospitalised 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.

Ghneim said the youth had been "carrying a sign to direct the traffic" when he was shot.
A total of 27 Palestinians were killed by the Israeli army in the West Bank in 2013, three times more than the previous year, figures from Israeli rights watchdog B'Tselem showed.
An army spokeswoman, contacted by AFP, said dozens of demonstrators hurled rocks and had approached the fence inside a military exclusion zone.
The soldiers first fired warning shots before targeting the protesters, she said, adding that at least one Palestinian was hit.
