The United States and the Gulf Cooperation Council (GCC) have called on Iran to immediately cease its nuclear provocations, engage in meaningful diplomacy, and fully cooperate with the International Atomic Energy Agency's (IAEA) investigations into particles of nuclear material found at undeclared locations in the country. A joint statement on February 17 by the United States and GCC member states noted that as documented by the IAEA, Iran's production of highly enriched uranium had no credible civilian purpose and was seriously exacerbating regional and global tensions.
