Iran courted new levels of post-election isolation from the European Union on Wednesday as European diplomats pondered whether to withdraw the ambassadors of all 27 member nations in a dispute over the detention of the British Embassys local personnel. European diplomats said that no formal decision to order their envoys home had been taken,but that the measure was an option under consideration as the European Union Irans biggest trading partner tries to work out how to defuse the dispute in a way that would shield other embassies in Tehran from similar action. Withdrawing all 27 ambassadors would represent a rare and unusually forceful display of European anger at Irans behaviour,and several diplomats said the European Union would prefer to avoid it. The initial Iranian response seemed characteristically bellicose. A high-ranking military official demanded that the Europeans apologise for interference in Irans affairs,which,he said,disqualified European countries from negotiating on the fraught issue of Irans nuclear ambitions. In a statement quoted by the Fars news agency on Wednesday,Irans chief of staff,Hassan Firouzabadi,was quoted as saying that because of EUs interference in the post-election riots,they have lost their qualification to hold nuclear talks with Iran. Before apologising for their huge mistake, he said,the European countries have no right to talk about nuclear negotiations,according to a Fars report. It was the first sign that Iran might use its post-election dispute to cast further doubt over the stalled nuclear negotiations,buying time to continue a nuclear enrichment programme. The Iranian authorities have especially sought to cast Britain as an instigator of the unrest. They arrested nine local employees of the British Embassy in Tehran over the weekend,though five were released by Monday night. The Iranian authorities accused the local employees of fomenting unrest. Press TV announced that three of the employees were released Wednesday,leaving just one still in custody. That employee,Fars said on Wednesday,had a remarkable role during the recent unrest in managing it behind the scenes. Carl Bildt,Swedens Foreign Minister,told reporters on Wednesday the day his country took over the rotating presidency of the European Union that it was in the interests of both the European Union and Iran to retain full diplomatic ties. But he did not specifically exclude the withdrawal of ambassadors,saying that from the diplomatic perspective,all options are on the table.
