Israel's prime minister has called on the US and its allies to "wake up" to the threat of Iran as talks continue to revive a landmark deal to limit the country's nuclear programme.
Naftali Bennett said Iran's "regime of brutal hangmen" wants nuclear weapons, something Iran has repeatedly denied.
Diplomats said progress was made to renew the deal, which the US withdrew from under President Donald Trump, but there were still gaps to be bridged.
Israel opposes the agreement.
Iran elected hardliner Ebrahim Raisi, the country's top judge who holds ultra-conservative views, as new president on Friday, in a race widely seen as being designed to favour him.
The president-elect - who will be inaugurated in August - is under US sanctions and has been linked to past executions of political prisoners.
