Israeli fire killed at least three Palestinians in two separate incidents across Gaza, local health authorities said, as tension rises over continued violence.
Medics said one Palestinian was killed in the Tuffah neighbourhood in Gaza City, in an area under Palestinian control, while two others were killed in the town of Bani Suhaila east of Khan Younis, an area Israel still occupies.
There was no comment from the Israeli military on the two incidents.
