The European Union and United States are set to toughen nuclear sanctions aiming to punish Iran while seeking to hold back Israel from a military strike, top officials said as the showdown enters a critical phase.
Western moves to pressure Iran have been made more urgent by Israeli Prime Minister Benjamin Netanyahu’s stern call for a “clear red line” against the Islamic state’s nuclear drive, diplomats said.
Netanyahu’s conversation with US President Barack Obama on Friday reassured some envoys that Israel and the United States are more in tune over Iran. But they highlighted lingering uncertainty about if and when Israel could launch unilateral action.
The European Union will be first to step up sanctions as part of the international campaign of pressure alongside increasingly frustrating efforts to negotiate a halt to Iran’s uranium enrichment.
Iran’s economy has been severely hit, particularly by action against its oil industry.
Its rial currency fell six percent to a new low of about 28,600 to the dollar on Saturday, according to exchange analysts. It has lost 60 percent of its value this year, while food prices have risen 50 percent.
The European Union ordered a ban on Iranian oil purchases from July 1, but Britain, France and Germany are “united” in pressing for additional sanctions by the 27-nation bloc, the official said.
A second senior official said the United States is also looking for “new areas” where sanctions could be applied or toughened.
The US Congress approved action in August targeting companies that work with Iran’s petroleum or natural gas sector, provides insurance to the National Iranian Oil Company, engages with uranium mining with Iran or sells oil tankers to the country.
Netanyahu’s speech to the UN General Assembly unnerved many. He warned that Iran could have the necessary material to make a bomb by mid-2013 and called for “red line” to stop Iran enriching uranium to the required purity for a bomb.
Netanyahu indicated that his deadline for a decision on action is now after the November 6 presidential election in the United States. But Israeli officials increasingly indicate their impatience with the sanctions path.
The first senior official noted that Western nations “have said to Israel that we are not in favor, in these circumstances when we are pursuing sanctions and negotiations, of any attack on Iran.”
The US administration “wants to pursue diplomacy, so we are nervous of any suggestion of any attack,” said the second official.
The trio of European nations plus the United States, Russia and China — the so-called E3+3 group — has sought to negotiate with Iran, which denies it seeks a bomb.
Ministers from the six nations met in New York on Thursday and again called on Iran to “urgently” show the proof that its intentions are peaceful.
Experts from the six are due to meet in London soon to “determine our negotiating position for any further meeting with the Iranians,” the first senior official said.
EU foreign policy chief Catherine Ashton said she would be contacting Iran to determined whether more negotiations should be held.
Alongside the sanctions and talks, the United States and Europe have also stepped up pressure on Iran over its support for Syria’s President Bashar al-Assad and militant groups in the region.
The United States is pushing Gulf states to develop missile defense plans, amid what they see as a rising threat from Iran, US officials said.
