US media: US-Iran mediators make final efforts to secure a 45-day ceasefire.

Four sources familiar with the negotiations from the United States, Israel, and the region revealed that the U.S., Iran, and a group of regional mediators are discussing the terms of a potential 45-day ceasefire agreement that could ultimately end the war. The sources said the chances of reaching a partial agreement within the next 48 hours are slim, but this last-ditch effort is the only chance to prevent a sharp escalation of the war. President Trump's 10-day deadline for Iran was originally set to expire Monday evening. However, Trump extended the deadline by 20 hours on Sunday and posted a new deadline on his social media platform, "Truth Social": 8 p.m. Eastern Time on Tuesday. Trump told AXIOS on Sunday that the U.S. is engaged in "deep negotiations" with Iran and that an agreement is possible before his deadline expires on Tuesday. (AXIOS)
