A peace proposal has been reportedly delivered to both the United States and Iran via mediators, urging a 45-day ceasefire and the reopening of the Strait of Hormuz, The Caspian Post reports, citing foreign media.

In an effort to stop the fighting, Egyptian, Pakistani and Turkish mediators have sent Iran and the U.S. a proposal calling for a 45-day ceasefire and the reopening of the Strait of Hormuz to give time to try and find a way to end the war, two Mideast officials have told The Associated Press.

Iran’s Foreign Ministry said Tehran’s position on a ceasefire had been conveyed to the other side through mediators and that exchanges of messages were continuing. Iranian officials have also signaled that the country remains wary of pressure tactics and has not committed to a temporary arrangement.

According to the reports, the proposal includes an immediate ceasefire as a first step, followed by negotiations on a broader framework that could address the wider conflict.

Trump has at times demanded that Iran reopen the strait or face a significant escalation in bombing from the U.S. while at other times said it was not up to Washington to force the waterway open or even that the war could end without it being reopened.

He has also given multiple deadlines to Iran on the issue, and after the threat he posted Sunday he later posted a single line saying “Tuesday, 8:00 P.M. Eastern Time!” It was not clear whether that meant he had extended the deadline another day.
