Iran expanded its nuclear program last year with continued uranium enrichment and growing infrastructure development, according to an annual CIA report to Congress.
The report on arms proliferation covering 2011, made public by the Office of the Director of National Intelligence (ODNI), reveals that Iran has produced 4,900 kilograms of low enriched uranium.
“Iran continued to expand its nuclear infrastructure and continued uranium enrichment and activities related to its heavy water research reactor” contrary to U.N. resolutions, the report says.
Disclosure of the report comes amid growing speculation that Israel will conduct a military strike against Iran’s nuclear facilities and other targets.
Underground centrifuge cascades—banks of devices that produce enriched uranium—at Natanz also progressed, with more advanced centrifuges tested and developed at a pilot plant.
