Thousands of Palestinians rioted along the northern Gaza security fence on Monday, the army said, as Palestinians reported that one man was shot dead by Israeli forces.
Some 3,000 people were throwing rocks and firebombs at Israeli troops across the border and attempting to damage the fence, according to the military.
Israeli soldiers were using tear gas and live fire against the rioters.
One Palestinian man, 27-year-old Muhammed Abu Abada, was shot dead by Israeli forces during riots near the town of Beit Lahia in northern Gaza, according to the Gaza health ministry, which is run by the Hamas terror group.
In addition, a group of Palestinian boats set sail from the coastal enclave toward the edge of the permitted fishing zone, apparently in order to break through the Israeli- and Egyptian-imposed naval blockade.
Israeli navy ships were at the scene, the IDF said.
On Sunday, the military said it carried out an airstrike targeting three Palestinians who were attempting to damage the fence in the border region between Israel and Gaza.
The army added that the Palestinians had apparently been “in the process of planting an explosive device” in the southern half of the Strip.
The Gaza health ministry pronounced the three Palestinians dead and identified them as 14-year-old Khalid Abu Said, 14-year-old Abdel-Hamid Abu Dhaher and 13-year-old Muhammed al-Satari.
On Monday, Aisha Abu Daher said her son Abdel-Hamid had “nothing to do with resistance” and denied her son had any links to terrorists.
The Islamic Jihad terror group vowed to “respond to this crime in a way that is proportionate to its size and the great fury it has caused among our people, nation and free people in the world,” according to a Palestine Today report.
It also denied that three teenagers had been involved in any type of “military action” in the border region.
“The occupation’s narrative is baseless, false and purely deceptive and fallacious,” the statement added.
Palestinian paramedics claimed the three bodies were found 200 meters from the fence.
Funeral processions took place in Gaza on Monday for the three teenagers.
Since March 30, Palestinians in the Gaza Strip have participated in a series of protests and riots dubbed the “Great March of Return,” which have mostly involved the burning of tires and rock-throwing along the security fence, but have also seen shooting attacks, bombings and attempted border breaches as well as the sending of incendiary balloons and kites into Israel.
At least 160 Palestinians have been killed and thousands more have been injured in the clashes with IDF troops, according to AP figures. Hamas, an Islamist terror group that seized control of the Strip in 2007 and seeks to destroy Israel, has acknowledged that dozens of the dead were its members.
