The landmark nuclear deal announced between the US and Saudi Arabia is dependent on Riyadh joining the Abraham Accords, in other words recognising the state of Israel, US President Donald Trump has said.

"The Civil Nuclear Deal (There will be no enrichment of material!)... which pertains only to non-military use... will be approved, but is totally subject to Saudi Arabia joining the very respected and successful Abraham Accords," Trump said in a post on Truth Social.

Trump's remarks come after criticism from experts that the deal could run the risk of future nuclear proliferation in an already unstable region.

The nuclear issue has been at the centre of the months-long US-Israeli conflict with Iran.

In 2020, Trump brokered the Abraham Accords, which secured the historic normalisation of relations between Israel and two Arab nations, the United Arab Emirates (UAE) and Bahrain.

Sudan and Morocco have since normalised relations with Israel.
