Qatari mediators were in Tehran on Friday to present the latest revisions to a draft proposal aimed at ending the US war with Iran and preventing renewed American military action, a source familiar with the negotiations confirmed to CBS News. 

According to the source, indications suggested progress was being made. Iran is expected to respond this weekend to a draft Qatari mediators presented last Sunday. 

President Donald Trump said Friday that he believed the war would end soon but did not explain how an agreement would be reached. 

“It’s going to get wrapped up soon,” President Trump said in ‌an ⁠interview with Kansas City radio station KCMO. “We need a guarantee there’ll never ⁠be a nuclear weapon.” 

Speaking ahead of next week’s midterm congressional elections, President Trump has said the US would not strike Iran before the elections. He has threatened military action against Iran multiple times in recent weeks. 

Diplomatic efforts have also included a message from US Vice President JD Vance to Mohsen Rezaei, secretary of Iran’s Supreme National Security Council and a former commander of the Islamic Revolutionary Guard Corps. Vance expressed his willingness last week to negotiate directly over a possible agreement to end the war. 

President Trump, however, denied instructing Vance to open negotiations, saying the communication instead involved Iran’s need for medical supplies. 

“No, what it is, is that they need help with medical supplies and various things,” Trump said when asked whether he had directed Vance to contact Iran. 

Meanwhile, 10 US transport aircraft arrived at Israeli Air Force bases in southern Israel as Washington and Jerusalem prepare for a possible renewed campaign against Iran, Kan News reported Thursday evening. 

After departing Fort Bliss in Texas, the aircraft landed at the Ovda and Nevatim bases. Fort Bliss houses one of the US military’s largest air defense centers and holds interceptors and air defense batteries. 

Their arrival raised the possibility that the aircraft were replenishing Israeli stocks or delivering additional air defense systems, including Patriot batteries. 

Other US transport aircraft also landed at bases in Jordan, Saudi Arabia and Qatar as part of a broader American airlift to the Middle East.
