An Iranian opposition group says UN sanctions will not stop Iran's government from pursing alleged plans to develop nuclear weapons.
The National Council of Resistance of Iran is urging the EU to cripple Iran's economy by implementing sweeping embargoes on the Iranian Central Bank and by banning all purchases of Iranian oil and gas.
Spokesman Shahin Gobadi says "the time has come for a firm policy on every aspect."
The call comes ahead of a meeting of EU foreign ministers on Monday, where the bloc is set to adopt sanctions against Iran's Revolutionary Guard and a number of companies allegedly involved in the nuclear program.
In June, the UN adopted a set of sanctions restricting trade on all items related to Iran's enrichment of uranium.
