The Palestinian health ministry had announced a fourth man had been killed but swiftly clarified that his heart had been restarted.
Earlier reports said Israeli troops fired tear gas and live bullets at Palestinians taking part in weekly protests at the Gaza Strip border with Israel on Friday, injuring at least 386 people, medics said.
The army said it was taking action to disperse some 10,000 Palestinians, some of whom threw rocks at the troops and burned tyres, and prevent any breach of the fortified frontier fence.
Israeli forces have killed at last 120 Palestinians in protests along the border since a campaign was launched on March 30 to demand the right to return to ancestral lands lost to Israel in the 1948 war of its creation, hospital officials say.
Israel says the dead included gunmen who used civilians as cover for gun and grenade attacks or infiltration attempts. Organizers linked Friday’s protests to annual “Jerusalem Day” events in Iran, which like Gaza’s dominant.
“There is no such state called Israel that could have a capital called Jerusalem,” Hamas spokesman Fawzi Barhoum said, adding that the protests, which also demand an end to a grinding Israeli and Egyptian blockade on Gaza, would continue.
Months of confrontation
There have been no Israeli casualties from the more than two months of confrontations along the Gaza border. But Israel says it has lost swathes of farmland and forests on its side of the border to blazes set by coal- or fuel-laden Palestinian kites.
Among those wounded on Friday was an Agence France Press photographer and a 23-year-old man who was on life support after a tear gas canister penetrated his face, medical officials said.
“We are not asking for the moon,” said Amer Abu Khalaf, a 20-year-old business administration student who took part in the protest, saying it aimed to “break the siege and have the world recognize our right to return”.
Israel has long refused to admit Palestinian refugees from the 1948 war or their millions of descendants, saying that would spell demographic suicide and that they should stay in a future Palestinian state. Statehood talks have been frozen since 2014.
The death toll from Israel’s lethal measures against the Gaza protests have drawn international censure, though the United States has placed the blame on Hamas.
