Israel proposed giving Hamas leader Yahya Sinwar safe passage out of Gaza in exchange for the group freeing the hostages it holds and giving up control of the strip, a senior official said, even as doubts deepen about the two sides’ ability to reach any cease-fire accord.

“I’m ready to provide safe passage to Sinwar, his family, whoever wants to join him,” Israel hostage envoy Gal Hirsch said in an interview Tuesday in the Bloomberg News Washington bureau. “We want the hostages back. We want demilitarization, de-radicalization of course — a new system that will manage Gaza.”
