U.S. and Iranian officials will hold indirect technical talks Wednesday regarding their deal to end the Middle East war, a diplomat familiar with the negotiations told Agence France-Presse (AFP).

"U.S. and Iranian officials are to hold indirect technical talks on Wednesday in Doha with Qatari and Pakistani mediators on the memorandum of understanding, building on the progress made at the Lake Lucerne Summit," the diplomat said.

U.S. envoys Jared Kushner and Steve Witkoff will not be taking part in the technical talks, the diplomat added, after they met with Qatar's Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani on Tuesday.

Both the U.S. and Iran had said they would send officials for meetings in Qatar.

The memorandum of understanding, brokered by Qatar and Pakistan, included a 60-day cease-fire in the war that started with U.S.-Israeli strikes on Feb. 28, the reopening of the blockaded Strait of Hormuz and a timeframe for a final deal to end the war and reach an agreement on Iran's nuclear program.
