Iran warned Tuesday it would start enriching uranium up to 60 percent purity, two days after an explosion it blamed on archenemy Israel hit its key nuclear facility in Natanz.The announcement cast a shadow over ongoing talks in Vienna aimed at salvaging the tattered 2015 nuclear deal between Iran and world powers that former U.S. president Donald Trump abandoned three years ago.Iran said it wrote to the United Nations’ International Atomic Energy Agency to announce “that Iran will start 60 percent enrichment,” a move later confirmed by the IAEA.The step will bring Iran closer to the 90 percent purity threshold for military use and shorten its potential “breakout time” to build an atomic bomb, a goal it denies.A handout picture provided by the Iranian presidential office on April 10, 2021, shows a videoconference with views of devices at Iran’s Natanz uranium enrichment plant, and Iranian President Hassan Rouhani speaking, in the capital Tehran.Under the nuclear deal, Iran had committed to keep enrichment to 3.67 percent, though it had stepped this up to 20 percent in January.The latest news came two days after an explosion knocked out power at Iran’s main nuclear facility at Natanz, which the Islamic republic blamed on Israel and labeled an act of “terrorism.”Israel, which did not claim responsibility, is strongly opposed to U.S. President Joe Biden’s efforts to revive the nuclear agreement.The accord between Iran and the U.N. Security Council’s permanent members plus Germany promised Tehran relief from punishing sanctions in return for agreeing to limits on its nuclear program.Israel has vowed it will stop Iran from ever building an atomic bomb, which it considers an existential threat to the Jewish state.The United States said it stood by Israel but remained committed to the Iran talks, despite Tehran’s enrichment plan.”We are certainly concerned about these provocative announcements,” said White House spokeswoman Jen Psaki.”We believe that the diplomatic path is the only path forward here and that having a discussion, even indirect, is the best way to come to a resolution.”Israeli-operated ship hitThe mysterious blast at Natanz has sharply heightened tensions between two powers already engaged in a shadow war on lands and seas across the Middle East.On Tuesday, an Israeli-operated ship was attacked off the United Arab Emirates, opposite the Iranian coast, Israeli media said, in the latest apparent tit for tat.Security sources, quoted by Israel’s Channel 12 television, said the vessel Hyperion Ray was “lightly damaged” near the Emirati port of Fujairah.Iran vowed Monday to take “revenge” for the Natanz attack.”If (Israel) thought that they can stop Iran from following up on lifting sanctions from the Iranian people, then they made a very bad gamble,” Foreign Minister Mohammad Javad Zarif warned.FILE – Iranian Foreign Minister Mohammad Javad Zarif listens during talks in Moscow, Jan. 26, 2021.Iran would make the enrichment plant “more powerful” by using advanced centrifuges, he added.Islamic Republic News Agency said Iran would also add “1,000 centrifuges with 50 percent more capacity to the machines present in Natanz, in addition to replacing” those damaged in the attack.”The preparations (for the implementation of this decision) will begin tonight” in Natanz, said the Atomic Energy Organization of Iran.The 60 percent enriched uranium would be used to “produce molybdenum for use in the manufacture of various radiotherapeutic products,” the organization added.Zarif, after talks with his visiting Russian counterpart Sergey Lavrov, also warned Israel’s ally the United States that it would gain no extra leverage in Vienna through “acts of sabotage” and sanctions.The White House has denied all U.S. involvement in the Natanz incident.Unsourced Israeli media reports attributed the blast to Israeli security services.The New York Times, quoting unnamed U.S. and Israeli intelligence officials, also said there had been “an Israeli role” in the attack, in which an explosion had “completely destroyed” the power system that fed the plant’s “underground centrifuges”.Quoting another unnamed intelligence source on Tuesday, The New York Times said an “explosive device had been smuggled” into the site and “detonated remotely,” taking out primary and backup power.Europe ‘bowing to America’s pressure’Lavrov, during his Tehran visit, stressed Russian support for Iran’s position.”We are counting on the fact that we will be able to save the agreement and that Washington will finally return to full and complete implementation of the corresponding U.N. resolution,” Lavrov said.Zarif blasted Europe’s “inability to implement” its nuclear deal commitments and “bowing to America’s pressure.”He also condemned the European Union for slapping sanctions on eight Iranian security officials, in response to a crackdown on 2019 street protests, saying the move threatens efforts to restore the deal.Lavrov’s remarks come at a time of heightened tensions between Russia and the West over various issues, including Ukraine.Iran President Hassan Rouhani told Lavrov that Iran expects a “return to 2015’s agreements and obligations.”For now, the agreement remains in limbo, with neither Tehran nor Washington backing down from its position, and each demanding the other make the first move.Russia’s ambassador to the U.N. in Vienna said the talks there have been postponed for a day until Thursday.The United States said it expects the talks to continue.”We expect and we have not been alerted of any change in planned attendance in meetings that will resume later this week,” said the White House’s Psaki.
