U.S. to send envoy to weekend talks with Iran
In a shift in U.S. policy, Undersecretary of State William Burns will join a meeting between European Union foreign policy chief Javier Solana and top Iranian nuclear negotiator Saeed Jalili.
They will discuss an offer made by world powers to Iran to give up its sensitive nuclear work that the West believes is aimed at building an atomic bomb. (Reporting by Sue Pleming; Editing by John O'Callaghan)
