Although the extent of the damage caused by the attack remains unclear, it coincided with negotiations between Tehran and world powers that sought the return of the US to the nuclear deal signed in 2015.

In response to the sabotage allegedly perpetrated by Israel, according to Iranian authorities, the Islamic Republic started to enrich uranium at 60 percent purity, three times more that what was previously achieved.

The sabotage and Iran’s latest decision stirred up tensions in the Middle East, where there is a low-profile war between Tehran and Tel Aviv.

The information disclosed by state television on the perpetrator of the sabotage did not say how he had access to one of the safest facilities in the country.

According to the report, authorities are carrying out actions to bring the suspect back, but they did not give details on these procedures.

Negotiations on how to save the Joint Comrephensive Plan of Action (JCPOA) or nuclear deal continued in Viena, Austria, on Saturday, especially on the lifting of US sanctions against the Islamic Republic.
