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.

But Iran said there were no talks planned for Sunday. Iranian Foreign Ministry Spokesperson Esmail Baghaei said there were no plans for an Iranian negotiating team to travel to Geneva or elsewhere in the next day or two, according to IRIB, Iran’s state broadcaster, The New York Times reported. While Iran could also sign electronically, it’s unclear if the signing event will happen.

One of the main reasons the signing will be virtual is that Vice President JD Vance, who has been negotiating the peace deal, wouldn’t be able to go to the signings and be back in the United States before Trump leaves for the G7 summit in France Monday, Axios said.

Also, Sunday is the president’s 80th birthday and the day of the UFC fight on the White House lawn.
