Iran warned on Saturday the West has until the end of the month to accept Teheran's counterproposal to a UN-drafted plan on a nuclear exchange, or the country will start producing nuclear fuel on its own.
The warning was a show of defiance and a hardening in Iran's stance over its controversial nuclear program, which the West fears masks an effort to make nuclear weapons.
Teheran insists the program is only for peaceful, electricity production purposes and says it has no intention of making a bomb.
"We have given them an ultimatum. There is one month left and that is by the end of January," Iranian Foreign Minister Manouchehr Mottaki said, speaking on state television.
