Iran began enriching uranium up to 60% purity Friday, its highest level ever, after an attack targeted its Natanz nuclear site, Parliament Speaker Mohamed Bagher Qalibaf told state TV.

The comment by Mohammad Bagher Qalibaf, quoted by state television, did not elaborate on the amount Iran planned to enrich. However, it is likely to raise tensions even as Iran negotiates with world powers in Vienna over a way to allow the U.S. back into the agreement and lift the crushing economic sanctions it faces.
The announcement also marks a significant escalation after the sabotage that damaged centrifuges, an attack this past weekend suspected of having been carried out by Israel. While Israel has yet to claim it, the country is widely suspected of having carried out the still-unexplained sabotage at Natanz, Iran's main enrichment site.
"The will of the Iranian nation is a miracle-maker and it will defuse any conspiracy," state television quoted Qalibaf as saying. He said the enrichment began just after midnight Friday.
The head of the Atomic Energy Organization of Iran, the country's civilian nuclear arm, later acknowledged the move to 60%, according to state TV. Ali Akbar Salehi said more details would be forthcoming and declined to further elaborate.
It wasn't clear why the first announcement came from Qalibaf, a hard-line former leader in the paramilitary Revolutionary Guard already named as a potential presidential candidate in Iran's upcoming June election.
While 60% is higher than any level Iran previously enriched uranium, it is still lower than weapons-grade levels of 90%.
Qalibaf announced on Twitter: "I am proud to announce that at 00:40 [Friday] … Iranian scientists were able to produce 60% enriched uranium."
On Wednesday, Iranian President Hassan Rouhani said Iran's move to enrich uranium up to 60% purity was a response to the sabotage at its key nuclear facility. Rouhani added that the Islamic Republic had no intention of building a nuclear weapon.
After an explosion at its Natanz uranium enrichment site on Sunday blamed by Tehran on archfoe Israel, Iran said it would begin enriching uranium at 60%, a move bringing the fissile material closer to levels suitable for a bomb.
It also said it would activate 1,000 advanced centrifuge machines at the site.
"Of course, the security and intelligence officials must give the final reports, but apparently it is the crime of the Zionists, and if the Zionists act against our nation, we will answer it," Rouhani said in a televised cabinet meeting.
"Our response to their malice is replacing the damaged centrifuges with more advanced ones and ramping up the enrichment to 60% at the Natanz facility."
