Iran has informed the International Atomic Energy Agency (IAEA) that the country's Natanz nuclear site was attacked on Saturday, though no increase in off-site radiation levels has been reported, according to the agency.
The IAEA said Saturday in a social media post that it is looking into the report.
IAEA Director General Rafael Grossi reiterated his call for military restraint to avoid any risk of a nuclear accident, the post said.
The IAEA has repeatedly warned that attacks on nuclear facilities could cause serious consequences for people's safety, the environment and regional stability.

The three astronauts aboard China's Shenzhou-23 spaceship have entered the country's Tiangong space station and met with their astronaut colleagues early Monday morning, as they now begin an in-orbit crew handover.
Mission commander Zhu Yangzhu and fellow astronauts Zhang Zhiyuan and Lai Ka-ying successfully entered the station's core module Tianhe after the spaceship made a fast automated rendezvous and docked with the Tianhe module at 02:45 (Beijing Time) on Monday.
The three Shenzhou-21 crew members opened the hatch at 05:13 (Beijing Time) and greeted the new arrivals, according to the China Manned Space Agency (CMSA).
The six astronauts then took group pictures for the eighth in-orbit get-together in China's aerospace history.
Notably, one of the Shenzhou-23 crew members is set to undertake a year-long stay aboard the space station, double the usual duration of previous Shenzhou missions.
The Shenzhou-23 spaceship, atop a Long March-2F carrier rocket, blasted off from the Jiuquan Satellite Launch Center in northwest China at 23:08 (Beijing Time) on Sunday.
Shenzhou-23 marks the 40th flight of China's manned spaceflight program and the seventh manned flight mission since the Tiangong space station entered its application and development phase in late 2022.
