A loud explosion and bright light in the sky in the area of the Natanz nuclear facility on Saturday night was an air defense drill, according to Iranian media reports.
Iran’s state-controlled Fars News Agency reported that the blast was caused by an air defense missile fired as part of the test. The drill was said to test the military’s rapid response to a possible attack.
“Such exercises are carried out in a completely secure environment … and there is no cause for concern,” military spokesman Shahin Taqikhani said.
The nuclear facility in Natanz is Iran’s primary center for enriching uranium.
Last week, the Jewish Chronicle reported that a group of Iranian scientists working at Natanz helped the Mossad sabotage the facility. In April, a number of centrifuges were destroyed in a mysterious explosion widely attributed to Israel.
On Friday, the U.S. suspended negotiations with Iran over returning to the JCPOA nuclear accord.
