Nine Palestinians were killed on Friday as Israel ignored calls for restraint in its use of force against unarmed protesters in Gaza for the second week in a row.
Israel's use of live ammunition has drawn condemnation from human rights groups, which say it is illegal under global law.
"The killing and wounding of yet more unarmed Palestinian protesters yesterday by Israeli forces in Gaza is an outrage. I know the situation is very, very hard", Israeli farmer Daniel Rahamim said about economic hardship in Gaza, the Palestinian enclave ruled by Hamas, an Islamist group that advocates Israel's destruction.
At least 9 Palestinians from the Gaza Strip were killed by Israeli forces during protests along the border with Israel, including a journalist and two minors.
The protest march last week, largely organised by Gaza's Hamas rulers, had been billed as the first of several weeks of intermittent protests against a stifling decade-old Israeli blockade.
Gaza's economy has been devastated by years of Israeli military attacks and a joint Israeli-Egyptian blockade. "And that if there is unjustified and unlawful recourse to firearms, resulting in death, that may amount to a willful killing", Elizabeth Throssell said in Geneva.
She said an attempt to approach or cross the "green-line" fence between Israel and Gaza itself certainly does not amount to a threat to life or serious injury that would justify the use of live ammunition.
Hamas has refused to give up its weapons - even at the cost of derailing talks on getting Abbas to assume the burden of governing Gaza, seen by Israel and Egypt as a prerequisite for opening Gaza's borders.

"I again stress 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", he added.
Israel has pledged to stop attempts to damage the heavily fortified fence on the Gaza border and to prevent illegal infiltrations, including with live fire if necessary.
Some have also called Friday's protest "Black Friday".
"Concerning rules of engagement, soldiers treat any activity putting Israel's security in danger as terrorist acts", he said. Hundreds more suffered other injuries, including tear gas inhalation, the officials said. They say they hope the tires will shield them from Israeli snipers.
Hamas has released photos that purport to show Israeli soldiers on the border within sniper range, sending the message that if it wanted to kill Israeli soldiers, it could.
