White House envoy Steve Witkoff said in a statement on Saturday that Hamas' response to his ceasefire and hostage deal proposal is "totally unacceptable and only takes us backward." Why it matters: Hamas didn't accept Witkoff's proposal as a basis for negotiations and demanded numerous changes that brought the negotiations once again to a deadlock.

Officials said Hamas was seeking changes on guarantees for a permanent end to war. That has long been the core sticking point with Israel.
