Israeli soldiers killed three protesters on the border today, including an 11-year-old boy, say Palestinian medical officials.
The army is said to have injured at least 248 other people who participated in weekly protests on the fortified border of the Gaza Strip on Friday.
The Israeli army says it used the necessary force to repel 13,000 Palestinians who gathered at several points on the fence.

The Israeli army says it used the necessary force to repel 13,000 Palestinians who concentrated at various points in the fence
Some threw stones, firebombs and grenades at troops under cover of smoke burned from burning tires, injuring a soldier, and nine Palestinians briefly crossed into Israel, he added.
Shadi Abdel-Al, 11, is the youngest victim of Israeli gunfire, while clashes continue amid protests that Israel says have been organized by Islamic rulers Hamas, which denies the accusation.
Shadi's father, Abdel-Aziz Abdel-Al, told Reuters today that his son had died as a martyr.
"I used to go every Friday to the marches like thousands of other people," he said. "This Friday it was his destiny to die as a martyr."
Another Palestinian, Hashem Hassan, 28, said he saw Abdel-Al being shot 70 meters from the fence, adding: "He threw some stones, which flew a few meters away, he did not pose any threat."
When asked about Abdel-Al's death, an Israeli military spokeswoman said only that the troops had complied with their open-fire regulations.

The dead today carry the number of Palestinians killed to 177 since violent demonstrations were launched on March 30 to file lawsuits against Israel.
Since March 30, Gaza has also seen bombings between Hamas's Islamist rulers in the coastal enclave and Israel.
A Palestinian sniper killed an Israeli soldier and Israel has lost tracts of forests and farmland to cross-border arson attacks.
The United States has backed its ally Israel in accusing Hamas of organizing the mass mobilization to divert attention from Gaza's governance problems and poverty and provide coverage for armed Palestinian border incursions. Hamas denies this.
The Israeli army said that twice this week, their patrols discovered and dismantled bombs that had been planted to be used against them in the fence.
Earlier today, several Palestinians crept into the fence to launch an air bomb at the troops, who responded with a gunshot, the army said. There were no news of casualties.
The protesters want rights over the lands that the Palestinians lost during the 1948 war in the founding of Israel, as well as the mitigation of the blockade that Israel, with the help of neighboring Egypt, has put in Gaza to isolate Hamas and deny its weapons .
US and Egyptian mediators have been trying to reach an agreement to calm Gaza, where Israel and Hamas have waged three wars in the last decade.
Brokerage efforts have become complicated due to Hamas's dispute with the Palestinian President backed by the West, Mahmoud Abbas, who has restricted funds to Gaza.
