A top Hezbollah official said Hamas revealed to the Iran-backed group how a last-minute decision to ditch phones in Doha saved them from an Israeli strike. The Israeli army attack targeted Hamas negotiators while they were studying Gaza ceasefire proposals on Wednesday.

The airstrike Tuesday has enraged Qatar, an influential U.S. ally that has been a key mediator throughout the war, and the attack has drawn heavy criticism across the Arab world.

Israeli Prime Minister Benjamin Netanyahu said on Saturday that getting rid of Hamas chiefs living in Qatar would remove the main obstacle to releasing all hostages and ending the war in Gaza.
