Iran announced Monday that it has passed the 3.67 percent uranium enrichment cap set under the Obama-era nuclear deal, Reuters reported.

Behrouz Kamalvandi, a spokesman for Iran's Atomic Energy Organization, told the IRIB news agency about the latest breach of the nuclear deal, Reuters noted.

“Twenty percent is not needed now, but if we want we will produce it. When we’ve put aside 3.67 percent enrichment we have no obstacle or problem with this action,” Kamalvandi is quoted as saying, according to the news service.
