U.S. and Middle Eastern mediators appeared optimistic in recent days that they were close to a deal.

But Israeli Prime Minister Netanyahu on Tuesday rejected Hamas's two main demands. Israel's offensive has killed more than 26,700 Palestinians, according to the Gaza Health Ministry. Hamas has refused to release any more hostages until Israel ends its offensive and withdraws from the Gaza Strip.. Iranian-backed groups in Lebanon, Syria, Iraq and Yemen have attacked Israeli and Israeli targets in support of the Palestinians, triggering retaliation.
