FACTBOX: Sanctions against Iran

(Reuters) - U.S. Secretary of State Condoleezza Rice warned Iran on Monday it faced more sanctions if it defied a two-week deadline to curb its nuclear program.

Following are some details about the sanctions and those imposed by the U.N. Security Council and the United States.

* WHAT DO NEW U.S. SANCTIONS INCLUDE?

-- A U.S. Senate panel this month approved legislation to strengthen U.S. sanctions on Iran. The measure would tighten the trade ban on goods to and from Iran. The bill also would expand financial sanctions on some individuals, and penalize U.S. companies if their foreign subsidiaries do business with Iran.

* WHAT DO NEW EU SANCTIONS INCLUDE?

-- They will target businesses and individuals that the West says are linked to Iranian nuclear and ballistic programs.

-- Visa bans on senior officials such as Revolutionary Guards head Mohammad Ali Jafari, Defense Minister Mostafa Mohammad Najjar and atomic energy chief Gholamreza Aghazadeh.

-- Iran's biggest bank, Bank Melli, will face an asset freeze, while visa bans will target "very senior experts" inside the nuclear and ballistic programs.

* WHAT SANCTIONS HAVE BEEN IMPOSED?

U.N. SANCTIONS:

-- The U.N. Security Council has imposed three sets of sanctions on Iran, in December 2006, March 2007 and March 2008.

-- The first covered sensitive nuclear materials and froze the assets of Iranian individuals and companies associated with the nuclear program. It gave Iran 60 days to suspend uranium enrichment, a process which can be used to make nuclear power plant fuel or bomb material. Iran did not stop.

-- The second included new arms and financial sanctions. It extended an asset freeze to 28 additional groups, companies and individuals engaged in or supporting sensitive nuclear activities or development of ballistic missiles.

-- State-run Bank Sepah and commanders and firms controlled by Iran's Revolutionary Guards, including commanders of one of its units, the Qods Force, were included on the list.

-- The resolution invoked Chapter 7, Article 41, of the U.N. Charter, which makes most of its provisions mandatory but excludes military action. Iran again failed to meet a 60-day deadline to halt enrichment.

-- On March 3, 2008, the Security Council imposed the third round of sanctions for refusing to suspend sensitive nuclear activities. Iran dismissed the move as illegal and illegitimate.
