Iran to boost centrifuges in Natanz

Iran has warned the IAEA about plans to increase the number of centrifuges at Natanz, Reuters reports.

IAEA inspectors visit Natanz regularly, according to a bilateral agreement. They are still restricted from visiting Parchin.

Uranium enriched to 20% is the main problem of the Iranian nuclear program. Experts say that it may be enriched to 90%, enough to build nuclear weapons.
