A Palestinian teenager died on Sunday, nine days after being wounded by Israeli fire during a Gaza protest against U.S. recognition of Jerusalem as Israel's capital, the health ministry said.
Mohammad Sami al-Dahdouh, 19, from Gaza City was shot on Dec. 15 during a demonstration on the Israeli border, ministry spokesman Ashraf al-Qudra said.
According to Palestinian health ministry, Dahdouh's death brings to 15 the number of Palestinians killed since U.S. President Donald Trump announced on Dec. 6 that he would recognize Jerusalem as Israel's capital and move the U.S. embassy there from Tel Aviv.
Among the Gazans killed in the Dec. 15 clashes was Ibrahim Abu Thurayeh, who had lost his legs in an Israeli attack a decade ago.
The health ministry in Gaza said the 29-year-old was shot in the head by a sniper, with the U.N.'s human rights chief saying he was "truly shocked" by Abu Thurayeh's death, demanding an "independent and impartial investigation."
On Dec. 18, the Israeli army said it conducted an investigation, according to which it was "impossible to determine whether Abu Thurayeh was injured as a result of riot dispersal means or what caused his death".
"No live fire was aimed at Abu Thurayeh," the army said in a statement.
On Saturday, the head of COGAT, Israel's defence ministry unit responsible for activities in the Palestinian territories, reiterated there was "no basis for the false reports that a sniper deliberately targeted Abu Thurayeh".
Major General Yoav Mordechai also wrote in a Facebook post in Arabic that he had asked the Red Cross to provide all information on Abu Thurayeh's evacuation and treatment.
"There are too many question marks around Abu Thurayeh's death," Mordechai wrote. "Let's put an end to the rumors, exaggerations and lies."
On Thursday, the U.N. General Assembly overwhelmingly passed a resolution against Trump's decision by 128-9 votes.
Jerusalem remains at the heart of the perennial Middle East conflict, with Palestinians hoping that East Jerusalem — occupied by Israel since 1967 — might eventually serve as the capital of an independent Palestinian state.
