US President Donald Trump is expected to withdraw backing from the nuclear accord with Iran on Friday and lay out a more confrontational strategy.
Trump poised to abandon Iran nuclear deal
STEPANAKERT, OCTOBER 13, ARTSAKHPRESS: The move would not withdraw the US from the deal but give Congress 60 days to decide whether to do so by re-imposing sanctions, BBC News reports.
Secretary of State Rex Tillerson has been consulting with counterparts in Europe and China, officials said.
Mr Trump has been under pressure at home and abroad not to scrap the deal.
Under the 2015 accord, Iran agreed to freeze its nuclear programme in return for the partial lifting of sanctions.
President Trump has been a longstanding critic of the deal and pledged to scrap it during his campaign.
President Trump has called the Iran nuclear accord the "worst deal ever negotiated", and threatened to tear it up.
Republicans have suggested they could use decertification as leverage to get the changes they want.
