Iran's nuclear negotiator Saeed Jalili has written to the European Union foreign affairs chief to announce the Islamic state's readiness for fresh nuclear talks with major powers, the foreign minister said on Sunday.

'A few days ago, Jalili's letter was sent to Ms Catherine Ashton saying Iran is prepared for talks to reach bilateral agreements,' Ali Akbar Salehi said in a news conference, when asked about Iran's nuclear work.

Iran's nuclear talks with major powers in January failed after the Islamic state refused to halt its uranium enrichment, as demanded by the United Nations Security Council.

The United States and its European allies fear Iran is trying to build atomic bombs under cover of its nuclear programme. Tehran denies it, saying it needs nuclear technology to generate electricity.

After talks with his European Union counterpart in Geneva in February, Salehi hoped there would be further meetings, but no date was set.
