At least 30 Palestinians were injured in clashes along the Gaza-Israel border as thousands gathered for a third consecutive Friday of protests.
"Media reports suggest that on Friday, Israeli soldiers will once again be ordered by high command - in contravention of worldwide law - to engage in sniper fire on Gaza residents who come within 300 meters of the border fence or engage in other non-life-threatening actions".
Israeli forces have killed 33 Palestinians and wounded hundreds of others since protests that began on March 30 and have led to clashes.
On Friday, most demonstrators assembled in five tent camps located several hundred meters (yards) from the border fence. Several dozen young men moved closer to the fence, some of them throwing stones.
An Israeli military spokesman said Friday its troops were "responding with riot dispersal means while also firing in accordance with the rules of engagement".
Palestinian organizers have called the series of protests the "Great March of Return" beginning on Land Day, March 30, and continuing until May 15, the 70th anniversary of the "Nakba" - or the "catastrophe" - when 750,000 Palestinians were forced out of their homes and off their land by Israeli forces in 1948.
In two weeks, 34 Palestinians were killed by Israeli fire, including 27 during protests. Israel has accused Hamas of trying to carry out border attacks under the cover of large protests and says it will prevent a breach of the fence at all costs.
They burned tires to create a shield of a black foggy smoke. they also burned Israeli flags and raised Palestinian ones.
Several thousand people gathered Friday at a tent camp east of Gaza City.
On Thursday, the IDF said it bombed Hamas military targets in the Gaza Strip, after an explosive device detonated near an Israeli army vehicle along the border on Wednesday.
In the camp, 37-year-old construction worker Omar Hamada said he is protesting to draw world attention to Gaza and get the border reopened.
Islam Herzallah, 28, died in hospital after being shot by Israeli troops east of Gaza City, the Health Ministry said.

Gaza's Health Ministry said more than 1,300 Palestinians were wounded by live fire in the past two weeks. It has said that soldiers fire live bullets as a last resort, in a "precise and measured manner".
The group has been criticised in Israel for publishing often anonymous testimony by current or former Israeli soldiers who have misgivings about their military service and treatment of Palestinians.
Rights groups have strongly criticised Israeli forces while pointing to unverified videos that have spread online of Gazans appearing to be shot, including one seeming to show a Palestinian targeted as he ran away from the fence while holding a tyre.
"The aim behind the demonstration is to support the Palestinian nation and to emphasise on the right of return (of Palestinian refugees to what is now Israel)".
"We fully support the efforts of Palestinian people in stressing their rights, their return, that their capital is Jerusalem and to oppose the conspiracy deal, the so-called century deal".
