June 13 (UPI) -- President Donald Trump and Pakistan have said that a memorandum of understanding extending the cease-fire between the United States and Iran will be virtually signed Sunday, though Iran has not confirmed the meeting.

Trump posted on Truth Social at 12:45 p.m. EDT Saturday: "The Deal is scheduled to get signed tomorrow, and immediately after it is signed, the Hormuz Strait is OPEN TO ALL."

He also posted a screenshot of a Saturday morning tweet by Pakistani Prime Minister Shehbaz Sharif: "We are closer to a peace deal than ever before. With finalization expected in the next 24 hours, Pakistan is preparing for the electronic signing of the peace deal immediately after, followed by technical level talks next week."

The Pakistani foreign minister confirmed that the signing was set for Sunday, Axios reported.
