(CNN) -- Long-stalled talks about Iran's nuclear program are set to resume in Switzerland Monday, one day after Tehran touted that it has everything needed to produce nuclear fuel.
Representatives from Iran and Germany will join those from members of the U.N. Security Council -- the United States, China, Russia, France and the United Kingdom -- at the meeting Monday and Tuesday in Geneva, said a spokeswoman for European Union foreign policy chief Catherine Ashton.
Mike Hammer, a spokesman for the National Security Council, said the talks will try "to underscore the concern of the entire international community in Iran's actions and intentions".
The so-called P5 plus 1 group has been meeting intermittently, with the last round of talks coming over a year ago. Its members have expressed strong and differing views on Iran's nuclear program.
Russia, for instance, is supplying fuel rods for Iran's Bushehr nuclear reactor. The United States and many of its closer allies, meanwhile, have voiced concerns that Iran is trying to make nuclear weapons -- something Tehran denies.
Iran already faces stiff sanctions from the international community, because it has continued to enrich uranium.
With the political barbs flying back-and-forth regularly, tensions raised even further Monday when bombers targeted two Iranian nuclear scientists.
Iran blamed Israel, the United States and the United Kingdom's spy agencies for the attacks, which killed Majid Shahriari and injured Fereydoun Abbasi. CNN
