"Three Israeli soldiers fired 20 bullets at the young man at close range," one witness told Anadolu Agency.
"He has since been taken to a hospital in Ramallah for treatment where he remains in critical condition," added the witness, speaking anonymously due to security concerns.
In a statement, the PRCS said as many as 60 people had suffered injuries during clashes that occurred in the West Bank cities of Jerusalem, Ramallah, Hebron (Al-Khalil), Bethlehem, Tulkarm and Jenin.
"Ten were injured by live ammunition, including two who are now in critical condition," the statement read.
"Twenty others sustained injuries from rubber bullets while 30 more suffered from excessive tear gas inhalation," it added.
At least four Palestinians have been martyred and hundreds injured in clashes with Israeli forces -- and at least one alleged airstrike -- since U.S. President Donald Trump announced his decision last week to recognize Jerusalem as Israel's capital.
At a Tuesday summit convened in Istanbul, the Organization of Islamic Cooperation responded to the U.S. move by recognizing East Jerusalem as the capital of Palestine.
Jerusalem remains at the heart of the Israel-Palestine conflict, with Palestinians hoping that East Jerusalem -- occupied by Israel since 1967-- might eventually serve as the capital of a Palestinian state.
In April, Russia recognized West Jerusalem as Israel's capital, voicing hope that the city's eastern half might eventually serve as the capital of an independent state of Palestine.
Trump, in his announcement last week, stressed that the "specific boundaries of Israeli sovereignty in Jerusalem" should be decided in final-status talks between the two sides.
