This brings up the number of Palestinians killed by Israeli forces since last Friday on the border with the Gaza Strip to 26.
Spokeswoman Elizabeth Throssell said in a news conference that Israeli forces were required under worldwide human rights law to use non-violent means "to the extent possible".
"The killing and wounding of yet more unarmed Palestinian protesters yesterday by Israeli forces in Gaza is an outrage". She also said there were "ominous statements" from Israeli authorities leading up to protests.
Last Friday was the bloodiest day of violence in Gaza since the 2014 war between Israel and Hamas, the militant group that controls the 140-square mile stretch of territory. Gaza's 2 million residents obtain just a few hours of electrical energy every day, faucet water is undrinkable and the shoreline has been polluted by tons of untreated sewage.
The IDF said it thwarted multiple efforts on Friday to breach the border fence - and that it used live fire to do so in some instances - as well as attempts to activate bombs against the troops under the cover of smoke from the protests.
Israel says its blockade is aimed exclusively at Hamas, and it has no quarrel with Gaza's civilians.More news: Malaysian PM announces dissolution of parliament amid crackdown on freedom of speech
A Palestinian journalist has succumbed to his wounds and died today after being shot in the stomach by an Israeli sniper on Friday.
Palestinian resistance faction Hamas on Saturday condemned the USA for vetoing a UN Security Council resolution calling for an investigation into Israel's acts of violence in the Gaza Strip.
Israel has drawn sharp criticism for its open-fire orders along the border, including its warnings that those approaching or trying to damage the fence would be targeted.
The UN chief also highlighted the urgency to accelerate efforts to "return to meaningful negotiations that will eventually allow Palestinians and Israelis to live in two democratic states side by side in peace and within secure and recognised borders".
Palestinians have marched to the fence as part of a six-week protest, dubbed "The Great March of Return", demanding the right to return for those driven out of their homeland.
Some have also called Friday's protest "Black Friday". Israel's army said it "does not intentionally target journalists".More news: Deadly fire in Trump Tower in Manhattan
"IDF troops fired toward them", the army said.
Mona al-Shaar, 43, who was distributing bottles of vinegar to protesters east of Khan Yunis to dab onto tissues to help them cope with tear gas, said: "We came here for the land and for a better future".
Unemployment is approaching 50 p.c, in line with official Palestinian figures.
Photos showed demonstrators running from tear gas fired by Israeli forces.
"There is no doubt stopping tire imports will have a negative effect on Palestinians in Gaza especially considering there is shortage of them there", he said.More news: 'Disgusting', Australian politician blasts indigenous focus at Games
