US President Donald Trump said on Monday that any agreement with Iran should include a requirement for several additional countries, including Saudi Arabia and Turkey, to join the Abraham Accords, the US-brokered agreements aimed at normalising relations with Israel that were forged during Trump’s first term.

In a social media post, Trump said negotiations are “proceeding nicely” but tied any eventual agreement to expanded participation in the agreements first signed in 2020.

He pointed to Saudi Arabia and Qatar as countries that should “immediately” sign on, followed by Pakistan, Turkey, Egypt and Jordan. Bahrain and the United Arab Emirates became the first countries to join in 2020.

He wrote that “after all the work done by the United States to try and pull this very complex puzzle together, it should be mandatory that all of these Countries, at a minimum, simultaneously, sign onto the Abraham Accords”.

The president said he brought up the Abraham Accords plan with leaders during negotiations on Saturday.

Trump suggested he may accept “one or two” countries declining to sign but said most should be willing. Egypt and Jordan already formally recognise Israel and have long-standing peace treaties.
