US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu spoke by telephone on Wednesday, and Iran was at the top of the agenda.
He repeated his earlier assertion that "Iran has always been secretly enriching".
The Kingdom's strongly worded statement came at a special session of the International Atomic Energy Agency (IAEA) Board of Governors meet held in Vienna following the two reports of IAEA Director General Yukiya Amano. He argued that American sanctions "should be seen as weapons of warfare" due to their "costly" consequences.
Trump and Netanyahu spoke on the telephone on Wednesday, with the U.S. president warning on Twitter of forthcoming "substantially" increased sanctions against Tehran over its announcement that it had exceeded a limit on enriched uranium reserves under the Joint Comprehensive Plan of Action (JCPOA).
Background: Last week, Iran announced that its stockpiles of low enriched uranium had exceeded the limits stipulated in the JCPOA.
The Washington Free Beacon reported that the increase in uranium levels has fueled tension between Iran and the Trump administration, which gave Tehran civil-nuclear waivers allowing it to build up its nuclear program.
"We are committed to denying Iran the benefits it seeks from these most recent provocations", she said. But they are grappling with whether - and how - to hit back, according to three USA officials.
With the United States withdrawing from the agreement in May 2018, the president "opened up the door to the nuclearization of Iran", he said.
The U.S. Trump administration and Israeli government say that components of the deal do not go far enough in imposing inspections on nuclear facilities, do not restrict the production of ballistic missiles, expire after just 10-15 years, and do not address Iran's destabilizing activity in the region, including its support of Hezbollah and Hamas along Israel's borders and Iran's own entrenchment in Syria.
