Israeli airstrikes killed at least 14 people in the Gaza Strip, hospital officials said Friday, while Hamas was reviewing a new Israeli-approved ceasefire proposal after giving it an initial cool response.

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.
