Iran says it is fully prepared to enrich uranium at any level

Iran said on Sunday it is fully prepared to enrich uranium at any level and with any amount, in further defiance of U.S. efforts to squeeze the country with sanctions and force it to renegotiate a 2015 nuclear deal with world powers.

At a news conference, Iranian officials said the process of raising uranium enrichment higher than set out in the pact would begin in a few hours.
