Iranian Foreign Minister Javad Zarif has blamed Israel on Monday for the sabotage of the Natanz nuclear site.
"The Zionists want to take revenge because of our progress in the way to lift sanctions ... they have publicly said that they will not allow this. But we will take our revenge from the Zionists," Zarif was quoted as saying by state TV.
According to Zarif, Israel "has publicly announced that it will not allow us to make progress in lifting restrictions, and it believes that it has succeeded in it."
Zarif went on to say that this "sabotage act" at the Natanz nuclear power plant will not weaken Tehran's position in the negotiations.
"The negotiating parties [in Vienna] should know that the Natanz reactor will henceforth be equipped with advanced centrifuges with high [uranium] enrichment capabilities," Zarif added.
Iranian foreign ministry spokesman Saeed Khatibzadeh later said that the Natanz attack was aimed at affecting JCPOA negotiations.
According to Khatibzadeh, IR-1 uranium enrichment centrifuges were damaged in the incident.
"If the Natanz attack was aimed at slowing down our nuclear production, it failed," the spokesman added, promising that "Israel will face a response in due time and place."
On the morning of April 11, an explosion occurred at a uranium enrichment plant in Natanz, in the Isfahan province in central Iran.
Head of Iran’s Atomic Energy Organization Ali Akbar Salehi defined the incident as an "act of nuclear terrorism," saying that Tehran reserves the right to respond to those responsible for the attack.
The explosion is reportedly a devastating blow to Iran's ability to enrich uranium and it could take at least 9 months to resume work in the facility.
Khatibzadeh, however, said that Iran will replace the damaged uranium enrichment centrifuges with more advanced ones. The attack will not slow down nuclear production in Iran, he said.
Later on Sunday The New York Times reported, citing unnamed sources within US and Israeli intelligence, that the incident was caused by a "deliberately planned explosion". The newspaper also claimed that the Natanz incident was a "classified Israeli operation".
The incident at the Natanz plant took place amid the Vienna talks dedicated to bringing back the US, which withdrew from the Joint Comprehensive Plan of Action (JCPOA).
The Israeli government has always been opposed to the nuclear deal, with Prime Minister Benjamin Netanyahu recently saying that Israel was not going to rely on the Iran nuclear agreement and would “do everything” to prevent Tehran from getting hold of nuclear weapons.
