At least nine charity workers have been killed and several others injured in an Israeli strike in Beit Lahia, northern Gaza, the enclave’s Government Media Office said Saturday, making it the deadliest incident since the ceasefire went into effect in January.

At least five Palestinians were killed, including two local journalists, and others wounded on Saturday in an Israeli strike on Gaza's northern Beit Lahiya town, medics told Reuters, as Hamas' leaders hold Gaza ceasefire talks with mediators in Cairo.

Hamas said Saturday it will only release an American-Israeli and the bodies of four other hostages if Israel implements their ceasefire agreement, calling it an “exceptional deal” aimed at getting the truce back on track.
