US 'greatly concerned' by IAEA report of Iran's increase in uranium enrichment

Iran's atomic energy chief says there is "nothing new" in the IAEA’s report saying that Tehran has reversed a months-long slowdown in its uranium enrichment programme.

WASHINGTON - The United States is 'greatly concerned' by an IAEA report of Iran's increase in production of highly enriched uranium, a White House national security council spokesperson said on Tuesday.

"Iran’s nuclear escalation is all the more concerning at a time when Iran-backed proxies continue their dangerous and destabilizing activities in the region, including the recent deadly drone attack and other attempted attacks in Iraq and Syria and the Houthi attacks against commercial shipping vessels in the Red Sea," the spokesperson said.

But Iran's atomic energy chief Mohammad Eslami said there was "nothing new" in the IAEA’s report saying that Tehran had reversed a months-long slowdown in its uranium enrichment programme, Iranian media reported.

"We did nothing new and are doing the same activities according to the rules," Eslami was quoted as saying.

An International Atomic Energy Agency report seen by Reuters on Tuesday said that Iran has "increased its production of highly enriched uranium, reversing a previous output reduction from mid-2023."
