In Iran, at the nuclear facility in Natanz, there was an accident related to electrical networks.
Reuters quoted Iranian media as saying that the day before, new and improved centrifuges for uranium enrichment were launched at the plant.
вЂњThe incident did not result in casualties or contamination,вЂќ said Behruz Kamalvandi, spokesman for the Atomic Energy Organization of Iran.
The cause of the accident is being determined.
The facility is central to Iran's uranium enrichment program and is monitored by IAEA inspectors.
Last July there was a fire there, which damaged one building, but no radiation emissions were detected.
The nuclear agreement with Iran was concluded in the summer of 2015. It provides permission for Iran to use nuclear power for peaceful purposes in exchange for Tehran's promise not to develop nuclear weapons. The parties agreed that Tehran would significantly limit its nuclear program in exchange for the West lifting economic sanctions.
In May 2018, then-U.S. President Donald Trump announced that his country was pulling out of the nuclear deal with Iran. Trump claimed вЂњundeniable evidenceвЂќ that Iran, contrary to assurances, was developing nuclear weapons. Since then, the U.S. has repeatedly expanded sanctions against Iran.
After the U.S. withdrawal from the Comprehensive Plan of Action on Iran's nuclear program, Iran began phasing out its obligations related to uranium enrichment and research activities, and in early January 2020 declared the end of the process.
On February 19 this year, the State Department reported that the administration of current U.S. President Joe Biden said it was ready to sit down at the negotiating table to reopen the nuclear deal with Iran.
In addition to the U.S. and Iran, China, France, Russia, Britain, and Germany will have to take part in the talks.
