Dozens of Palestinians have been injured during protests along the border with Israel, Gaza's Health Ministry has said.
It said most of the 86 people injured were treated for tear gas inhalation, while some sustained gunshot wounds.
Israel's military said Palestinians tried to damage the border fence, rolled burning tyres and threw an explosive device at soldiers. It said troops responded with tear gas and live fire.
Leaders of Hamas, the Islamic militant group that rules Gaza, visited protest tents near the border and vowed to continue the weekly rallies it is leading.
More than 110 Palestinians have been killed by Israeli fire since demonstrations began on March 30.
Israel says it is defending its border as well as its communities nearby. It accuses Hamas of trying to carry out attacks under the guise of protests.
