The Kabul Tribune (KT) – The United States and Iran have received a proposed framework to end hostilities, but Tehran has rejected reopening the Strait of Hormuz as part of an initial ceasefire, a senior Iranian official told Reuters on Monday.

The plan outlines a two-step approach, beginning with an immediate ceasefire followed by a comprehensive agreement to be finalized within 15 to 20 days, a source familiar with the discussions said.

However, the Iranian official said Tehran would not reopen the key shipping route under a temporary truce and would not accept deadlines while reviewing the proposal, adding that Washington lacks readiness for a permanent ceasefire.

The developments come after U.S. President Donald Trump warned Iran he would bring “hell” to Tehran if a deal is not reached by the end of Tuesday.

Meanwhile, Pakistan’s army chief, Field Marshal Asim Munir, has been in contact overnight with U.S. Vice President JD Vance, U.S. envoy Steve Witkoff and Iranian Foreign Minister Abbas Araqchi as part of ongoing diplomatic efforts, the source said.

Axios first reported that the United States, Iran and regional mediators were discussing a potential 45-day ceasefire as part of a broader deal that could lead to a permanent end to the conflict.
