Israeli airstrikes killed at least 38 Palestinians in Gaza, hospital officials said on Sunday, as Israel’s military said it has struck over 100 targets in the embattled enclave in the past day. The fighting came as Israeli Prime Minister Benjamin Netanyahu was preparing to fly to Washington for talks at the White House to push forward ceasefire efforts.

President Donald Trump has floated a plan for an initial 60-day ceasefire that would include a partial release of hostages held by Hamas in exchange for an increase in humanitarian supplies allowed into Gaza. The proposed truce calls for talks on ending the 21-month war altogether.

The Israeli military had no immediate comment on the individual strikes, but said it struck 130 targets across the Gaza Strip in the last 24 hours. It said the strikes targeted Hamas structures and a number of militants had been killed.
