The airstrike comes three days after three Palestinian teens were killed by an Israeli airstrike near the southern Gaza border fence. The Israeli military said they had attempted to damage the border fence and "were apparently involved in placing an improvised explosive device" near it. Ashraf al-Kidra of the Health Ministry says ambulance crews are bringing the bodies of the boys, aged 12 to 14, to a hospital from the perimeter fence dividing Gaza and Israel.
Omar Shakir, Human Rights Watch director in Israel and the Palestinian territories, said the killing of the boys appeared to be a violation of human rights law.
The Gaza envelope settlers have also demonstrated on Sunday in Tel Aviv to protest against the deterioration of the security situation in the settlements and closed some main roads in Tel Aviv.
Fatma Abu Isied said her 13-year-old nephew, Khaled, used to go to the open space along the border to catch birds.
Ibrahim al-Satari, the father of 13-year-old Mohammed, said he couldn't understand it.
Alon Schvartzer, director of Policy for Im Tirtzu, said that they arrived to show solidarity with the people of the south. "These are small children", he said.
He said that dozens injured by gunfire and others suffered suffocation after inhaling tear gas fired by Israeli soldiers at Palestinians demonstrating on the beach.
Mohammed abu Abada, 27, was shot in the chest in protests along the border near Beit Lahia in northern Gaza, a health ministry spokesman told AFP.
At least 217 Palestinians have been killed by Israeli fire in the months of demonstrations.
Israel justifies its blockade by the need to contain Hamas and accused the islamist movement that runs the enclave of orchestrating the protests for "terrorists".
