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.

The United Nations, human rights groups and some scholars have condemned the idea of removing people from their homeland in the Gaza Strip.

Israeli Prime Minister Benjamin Netanyahu on Monday backed a proposal by President Donald Trump to relocate Palestinians from Gaza and turn the war-ravaged coastal enclave into a luxury waterfront development—a plan that has drawn international condemnation and could further complicate fragile cease-fire talks between Israel and Hamas.
