Ali Akbar Salehi, the head of Iran’s Atomic Energy Organization says that if Iran decides to, they can restart 20 percent uranium enrichment in 3 or 4 days.

This is the second time in less than a week that Salehi is talking about returning to 20 percent enrichment.

Salehi had previously warned that if Iran and Europe do not reach an agreement over JCPOA after the United States’ exit, Iran will restart its 20 percent enrichment of uranium.

Salehi’s comments were in response to John Bolton’s recent claim that Iran has provided false information to the IAEA.

Bolton’s claim is based on the new report by Institute for Science and International Security. He also stated that the president of the United States was right to end his participation in the terrible Iran nuclear deal.

According to Bolton, pressures on Iran will increase until Tehran will stop its “nuclear ambitions”.

The report was prepared by using the new documents that Israel stole from Iran’s nuclear archive.

The documents provide key information regarding Iran’s nuclear activities for building a bomb.

Javad Zarif, Iran's foreign minister has denied all these allegations.
