Israel launches attack on Arak heavy water nuclear facility

Iran’s Atomic Energy Organization confirmed on Thursday that Israel launched an attack targeting the Arak Heavy Water Nuclear Facility, also known as the Shahid Khondab Research Reactor, located in Iran’s central Markazi province.

The incident has been formally reported to the International Atomic Energy Agency (IAEA), Iranian officials said, calling the Israeli action a dangerous escalation in the ongoing conflict with the Zionist regime.

Israel has attacked Iran’s Arak heavy water reactor, Iranian state television said Thursday.

The report said there was no radiation danger whatsoever and that the facility had already been evacuated before the attack.

The Israeli military said Thursday’s round of airstrikes targeted Tehran and other areas of Iran, without elaborating. It later said Iran fired a new salvo of missiles at Israel and told the public to take shelter.

A military spokesperson later said Israeli forces struck nuclear sites in Bushehr, Isfahan and Natanz, and continue to target additional facilities. Bushehr is Iran’s only operating nuclear power plant, which sits on the Gulf coast.

Israel had warned earlier it would attack the facility and urged the public to flee the area. The warning came in a social media post on X. It included a satellite image of the plant in a red circle like other warnings that preceded strikes.

Israel’s seventh day of airstrikes on Iran came a day after Iran’s supreme leader rejected US calls for surrender and warned that any military involvement by the Americans would cause irreparable damage to them. Israel also lifted some restrictions on daily life, suggesting the missile threat from Iran on its territory was easing.

Already, Israel’s campaign has targeted Iran’s enrichment site at Natanz, centrifuge workshops around Tehran and a nuclear site in Isfahan. Its strikes have also killed top generals and nuclear scientists.

The Arak heavy water reactor is 250 kilometers southwest of Tehran.

Heavy water helps cool nuclear reactors, but it produces plutonium as a byproduct that can potentially be used in nuclear weapons. That would provide Iran another path to the bomb beyond enriched uranium, should it choose to pursue the weapon.

Iran had agreed under its 2015 nuclear deal with world powers to redesign the facility to relieve proliferation concerns.

In 2019, Iran started up the heavy water reactor’s secondary circuit, which at the time did not violate Tehran’s 2015 nuclear deal with world powers.

Britain at the time was helping Iran redesign the Arak reactor to limit the amount of plutonium it produces, stepping in for the US, which had withdrawn from the project after President Donald Trump’s decision in 2018 to unilaterally withdraw America from the nuclear deal.

The International Atomic Energy Agency, the United Nations’ nuclear watchdog, has been urging Israel not to strike Iranian nuclear sites. IAEA inspectors reportedly last visited Arak on May 14.
