Israel has spied on Iran's nuclear talks with the United States and other major powers, the Wall Street Journal reported Tuesday. Israel quickly dismissed the report as "**t true", and denied spying on the United States. The Journal report, quoting current and former US officials, said the operation was designed to infiltrate the talks and help build a case against the emerging terms of a deal. Besides eavesdropping, Israel obtained information from confidential US briefings, informants and diplomatic contacts in Europe, the officials told the Journal.
