DUBAI: Iran has made 6.5kg of uranium enriched to up to 60 per cent, the government said on Tuesday, detailing a move that rattled the country's nuclear talks with world powers by taking the fissile material a step towards nuclear weapons-grade of 90 per cent.

Government spokesman Ali Rabiei was quoted by state media as saying the country had also produced 108 kg of uranium enriched to 20 per cent purity, indicating quicker output than the rate required by the Iranian law that created the process.
