The US has no problem with Iran's Russian-built Bushehr nuclear reactor plant but with other sites where weapons work may be underway, US Secretary of State Hillary Clinton has said.
Iran has started loading fuel into the core of its first nuclear power plant at Bushehr, its atomic energy chief said,. It is the last major step to realising its stated goal of becoming a peaceful user of nuclear energy.
"I heard some of the news coverage that, you know, oh my goodness the Iranians are starting their reactor. That is not the issue," Clinton told reporters at a meeting with Austrian Foreign Minister Michael Spindelegger.
"They are entitled to peaceful civilian nuclear power. They are not entitled to nuclear weapons," Clinton added.
Iranian officials said Bushehr showed Iran's nuclear plans are on track despite UN, US and European Union sanctions aimed at forcing it to curb uranium enrichment, which many countries fear is aimed at developing atomic bombs.
Clinton added that there were signs Iran was ready to come to the negotiating table.
