Iran's Nuclear Safety Centre said investigations found no evidence that Israel used depleted uranium munitions during the recent 12-day conflict between the two countries, IRNA reported on July 8.

"We inform the respected Iranian people that in the studies conducted so far, no signs of the use of depleted uranium have been discovered," Iran's state broadcaster quoted from the centre's statement.

The announcement follows reports by Fars news agency on June 26, citing sources claiming Israeli forces may have used depleted uranium ammunition in strikes on Iranian facilities during the conflict.

Israel launched a military operation against Iran on June 13, with the Islamic Republic conducting a retaliatory attack less than 24 hours later. The United States entered the conflict nine days after escalation began, with American forces attacking three Iranian nuclear facilities on June 22.

Iran responded on June 23 with missile strikes on the Al-Udeid Air Base in Qatar, the largest US military installation in the Middle East. US President Donald Trump later announced that Israel and Iran had agreed to a complete ceasefire, which took effect on June 24.

Iran's Nuclear Safety Centre conducted comprehensive analyses of strike sites to determine whether depleted uranium weapons had been employed. Depleted uranium munitions are controversial due to their radioactive properties and potential long-term health and environmental impacts.

The investigation's findings contradict earlier speculation about Israel's use of such weapons, which are primarily employed for their armour-piercing capabilities due to depleted uranium's density and hardness.

Iran's announcement comes as both countries work to maintain the ceasefire brokered by the United States following the brief but intense military exchange that raised fears of broader regional conflict.

The Nuclear Safety Centre's statement aimed to reassure the Iranian public about potential radiation exposure from the Israeli strikes whilst addressing concerns raised by the Fars agency's earlier reports.
