Vice President Vance met Friday with Qatari Prime Minister Sheikh Mohammed Bin Abdul Rahman al-Thani, a key mediator, as the U.S. awaits Iran's response to a draft agreement to end the war. The Qatari premier traveled to Washington solely for the meeting and departed immediately afterward.

The White House views Qatar as especially effective in negotiations with Iran, according to U.S. officials, though Pakistan has served as the official mediator since the conflict began. The Qataris have continued working behind the scenes, resuming their mediation efforts several weeks ago.

The White House is waiting for Iran's response to a one-page memorandum of understanding (MOU) designed to end the war and establish a framework for more detailed nuclear negotiations. Secretary of State Rubio told reporters Friday that he expected Iran to send its response today.

"We'll see what their response entails. The hope is it's something that can put us into a serious process of negotiation. I hope it's a serious offer. I really do," Rubio said. The outcome could determine whether the parties move toward a ceasefire or face continued hostilities.

The meeting underscores the complex diplomatic landscape, with multiple mediators operating simultaneously. A successful response from Iran could open the door to broader talks, while a rejection risks prolonging the conflict.
