May 25 (Reuters) - The U.S. and Iran are discussing a plan to open the Strait of Hormuz about 30 days after the two countries reach a deal to end hostilities, the Nikkei newspaper reported on Monday citing a Middle East diplomatic source.

Iran would proceed to clear mines from the strait during a 30-day window following an agreement, after which ships from all countries would be able to navigate freely and safely, and Iran would stop collecting transit fees, Nikkei said.

The ceasefire agreed in early April would be extended for 60 days, with the plan to hold talks on Iran's nuclear program during the two-month pause, the report added.
