White House: Reviewing Iranian letter on nuclear talks

The White House offered a cautious response on Thursday to an Iranian letter to world powers on resuming talks about its nuclear program, but repeated there was "time and space" for diplomacy to resolve tensions between Tehran and the West.

"We're reviewing the letter," said White House press secretary Jay Carney. "The Iranians needed to respond to that letter (from world powers) and so they have, but I don't want to make any qualitative judgements about their response at this time," he told reporters. (Reuters)
