Iranian President Hassan Rouhani says his country has launched a new generation of centrifuges that are used for uranium enrichment.
Rouhani's statement came on Saturday at an event attended by engineers involved in nuclear development.
He said Iran has started operating new high-performance centrifuges at a nuclear facility in Natanz. He added that Iran will start technical tests of another type of centrifuge.
He also said Iran will not let anyone in the world say its nuclear development is unlawful.

Indirect talks between the United States and Iran, brokered by the European Union and other relevant countries, started this month.
The administration of US President Joe Biden hopes to rejoin the nuclear deal which his predecessor Donald Trump withdrew from.
Iran is demanding all sanctions that were re-imposed by the Trump administration be lifted, but the United States is refusing.
Iran is believed to be putting pressure on the United States by showing its determination to step up the country's nuclear development activity.
