The European Union has received Iran's invitation to view its nuclear sites, but wants the International Atomic Energy Agency (IAEA) to be involved, officials in Brussels said Tuesday, dpa reported.
"We can confirm receipt of the letter by our ambassador to the IAEA ... It is for the IAEA and its inspectors in the first place to have full access to Iran's facilities and do the necessary assessments of the Iranian nuclear programme," a spokesman for the European Commission said.
Three of the EU's biggest powers - Germany, Britain and France - are involved in talks on Iran's nuclear programme, and the bloc's foreign policy chief, Catherine Ashton, negotiates on behalf of the trio plus China, Russia and the United States (the "E3+3 group").
The parties are due to meet in Istanbul at the end of January.
"We will respond in due course after consulting with our international partners ... What is also needed is that progress is made in the resumed dialogue between E3+3 and Iran," the spokesman said.
