TEHERAN, Iran — Seven international envoys on Saturday started a tour of two key Iranian nuclear sites that in an effort that Teheran hopes will build support ahead of more talks on its disputed atomic work.
In a blow to the effort, key powers Russia, China and the European Union refused the invitation. The EU said it should be up to inspectors from the UN atomic agency to verify whether Iran's program is entirely peaceful. The United States was not invited.
On the tour are envoys from Egypt, Cuba, Syria, Algeria, Venezuela, Oman and the Arab League.
