US Secretary of State John Kerry on Wednesday hit out at a letter by Republican senators to Iran against the nuclear talks he is leading, saying it threatened global trust in America.

"This risks undermining the confidence that foreign governments in thousands of important agreements commit to," Kerry told US lawmakers, adding he had reacted with "utter disbelief" to news of the letter, which comes as he prepares to return for further intense negotiations reaching the critical end-stage.
