Israeli military strikes have killed at least 14 Palestinians in the Gaza Strip over the past 24 hours, the enclave's Health Ministry said on Sunday, as Arab and U.S. mediators work to shore up a fragile ceasefire between Israel and Hamas.

At least nine people 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 a ceasefire went into effect in January.

The Al-Khair Foundation says staff were setting up a camp for displaced Gazans in Beit Lahia Saturday when back-to-back Israeli strikes hit their vehicles.
