Israeli airstrikes hit about 40 targets across the Gaza Strip over the past day, the military said on Friday, hours after Hamas rejected an Israeli ceasefire offer that it said fell short of its demand to agree a full end to the war.

Israeli airstrikes across Gaza killed at least 25 people on Friday including children, hospital workers said, as the new U.S. ambassador to Israel made his first public appearance in Jerusalem.

A new wave of Israeli strikes across Gaza kills more than 20 people, including an attack on the last major hospital providing critical healthcare in the north.
