A Palestinian official says Israeli troops have shot dead three Palestinians, including a 91-year-old man and his teenage grandson, in Gaza.
"Ibrahim Abdullah Abu Saeed, a caretaker at a a farm, aged 91, and Ismael Walid Abu Audeh, 20, were killed on Sunday by fire from an Israeli tank," Adham Abu Salima, a spokesman for local medical services, told AFP.
Shortly after, the caretaker's 17-year-old grandson, Hossam Khaled Abu Saeed, also died of wounds sustained in the incident, close to the Gaza-Israel border, medics said.
A spokesperson for the Israeli Army confirmed the shooting, AFP reports, saying troops opened fire at a group of suspects preparing to fire a rocket-propelled grenade at Israel.
The spokesperson says that the incident is the second at the border and that earlier troops had fired warning shots at a group of men approaching the frontier fence.
Earlier in the day a rocket fired from Gaza struck Israeli territory but did not cause casualties or damage.
At least seven rockets or mortar rounds have hit Israel in the past week, and on Friday Israel launched a series of reprisal air raids - mostly targeting smuggling tunnels - that wounded two members of the Hamas security forces.
