Iran can enrich enough weapons-grade uranium for a single nuclear bomb in about a month, according to an estimate by a nuclear non-proliferation think tank released late Wednesday.

The report, by the Washington-based Institute for Science and International Security, claims Iran has significantly shortened the time needed to “break out” to a nuclear bomb with the installation of new centrifuges in the Fordo and Natanz plants, and advanced IR-2 machines at Natanz.
