The U.S., Iran and a group of regional mediators are discussing the terms for a potential 45-day ceasefire that could lead to a permanent end to the war, according to four U.S., Israeli and regional sources with knowledge of the talks.
Why it matters: The sources said the chances for reaching a partial deal over the next 48 hours are slim. But this last-ditch effort could be the only chance to prevent a dramatic escalation in the war that will include massive strikes on Iranian civilian infrastructure and retaliation against energy and water facilities in the Gulf states.
