The White House said Thursday that the U.S. has submitted a new Gaza ceasefire proposal that has Israeli support. Hamas officials gave the Israeli-approved draft a cool response, but said they wanted to study the proposal more closely before giving a formal answer.

President Donald Trump’s Mideast envoy had expressed optimism this week about brokering an agreement that could halt the Israel-Hamas war, allow more aid into Gaza, and return more of the 58 hostages still held by Hamas, around a third of whom are alive.
