Iran Will Revise Un Nuclear Watchdog Ties State Media

Iran insists it wants only atomic energy, but a number of Western countries suspect it of trying to build nuclear weapons.

On Wednesday, the UN Security Council voted to impose a fourth round of sanctions on Tehran for failing to halt its nuclear enrichment programme.

The measures were passed after being watered down during negotiations with Russia and China.

Beijing said on Thursday it "highly values" its relations with the Islamic republic, after incurring Tehran's anger by voting for the measures.

Meanwhile, Russia said the sanctions meant it could not supply Iran with the S-300 anti-missile system Tehran had ordered, a military source told Moscow's Interfax news agency.

"It is compulsory to fulfil a decision by the UN Security Council, and Russia is not an exception here," said the unnamed source in the Federal Service for Military Technical Co-operation, which supervises Russian arms sales, reports AFP news agency.

"Naturally, the contract for the delivery to Tehran of the S-300 air defence missile systems will be frozen," added the source, who was not named. There was no official confirmation of the comments.

Russia agreed the S-300 deal with Iran several years ago, but has never delivered the weapons, under pressure from the US and Israel.

The new UN resolution includes measures to prohibit Iran from buying heavy weapons such as missiles and helicopters.

The Security Council voted by 12 votes to two in favour; Brazil and Turkey voted against, while Lebanon abstained.

They argued that the move was counter-productive and endangered a diplomatic solution.

Turkish Prime Minister Recep Tayyip Erdogan said on Thursday that the imposition of the latest sanctions was a "mistake", reports Reuters news agency.

Although the measures were not as tough as the US had wanted, President Barack Obama said they sent an unmistakable message about the determination to stop the spread of nuclear arms.

However, President Mahmoud Ahmadinejad said the UN's resolutions were like a "used handkerchief which should be thrown in the dustbin. They are not capable of hurting Iranians".

BBC Middle East editor Jeremy Bowen says the most significant parts of the resolution create a legal basis to restrict the supply of goods that Iran wants for its alleged nuclear missile programmes.

Our correspondent says the measures single out the Iranian Revolutionary Guards, who run much of the economy - including the national shipping line, which Western diplomats say is trying to evade sanctions by setting up front companies.

The resolution toughens rules on financial transactions with Iranian banks, and increases the number of Iranian individuals and companies that are targeted by asset freezes and travel bans.
