Iran's Supreme Leader Ayatollah Ali Khamenei's claim that the US is “lying” about the terms of a framework nuclear agreement will not derail the negotiations, the White House said.

“The test of whether or not that framework can be memorialized in a deal is not going to be a comment on any given day by a particular Iranian leader,” Sky News quoted deputy national security adviser Ben Rhodes as saying.

Whether a final deal is reached will depend on the ability of negotiators from the US, Iran and five other world powers to produce a document by the end of June that “meets our core objectives of preventing Iran from getting a nuclear weapon,” Rhodes said.

Khamenei on Thursday accused the US of publishing a fact sheet about the framework agreement that misrepresented what was agreed to, particularly on the pace of sanctions relief and inspections of nuclear sites.
