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.
Fighting has largely abated since Israel and Hamas agreed to a ceasefire in October, two years into the war, but it has not stopped entirely. The two have traded blame over the violations of the deal.
A Hamas official told Reuters on Sunday that the group urged mediators to intervene to stop "daily Israeli killings that aim to derail the ceasefire deal."
More than 440 Palestinians, most of them civilians according to Gaza health officials, have been killed since the truce, as well as three Israeli soldiers.
