Israel and Hamas are considering a new U.S.-backed ceasefire proposal that would pause the war, free Israeli hostages and send much-needed aid into Gaza.

The war started after Hamas attacked Israel on October 7 2023, killing around 1,200 people and taking 251 hostage. Most of the hostages have been released in earlier ceasefires. Israel’s offensive in Gaza has killed more than 57,000 Palestinians, more than half of them women and children, according to Gaza’s health ministry.

President Donald Trump’s foreign envoy Steve Witkoff said Tuesday that he’s hopeful to have a Gaza ceasefire deal by the end of the week, as negotiators make substantial progress working through remaining issues.
